Video: What Chick Shipping Day Looks Like at the Hatchery

The first time you order chicks, the strangest part is picturing them in a cardboard box, riding through the postal system without you. It feels like it shouldn’t work. Yet chick shipping has been routine in the United States for over a century, and the whole process is built around one simple fact about how baby birds are made.

This guide follows one box of chicks through a typical shipping day: the hatch, the sorting table, the packing line, the post office, and the moment the phone rings at your house. You’ll learn why the chicks are fine in there, what the hatchery does to keep them that way, and the handful of things you control once the box leaves the building.

What Happens on Chick Shipping Day?

Chick shipping day is really the last day of a three-week project. The eggs have been in an incubator for about 21 days (for chickens), and the goal is to get the chicks from the hatcher into the mail while they are still living off their built-in food supply. At a hatchery, chicks typically hatch, get sorted, get packed, and leave by mail within the same short window, so they spend as little of their travel reserve as possible before the trip begins.

Here is the rough shape of the day. Exact timing varies by hatchery and season.

Stage	What happens	Why it matters to you
Hatch	Chicks finish hatching and dry off in the hatcher	The travel clock starts here
Pull and sort	Chicks are removed, checked, and grouped by breed	Weak or unhealthy chicks are not packed
Sex and count	Sexed orders are separated; every order is counted	You get the mix you ordered
Pack	Chicks go into ventilated, bedded shipping boxes	Box size and chick count keep them warm
Mail	Boxes are handed to the postal service	Your pickup window starts when the box lands locally

Why Can Day-Old Chicks Travel Without Food or Water?

Just before a chick hatches, it draws the remaining egg yolk into its belly. That yolk is a packed lunch. The absorbed yolk gives a newly hatched chick enough nourishment and hydration for up to about 72 hours, which is why day-old poultry can legally and safely travel by mail.

The U.S. Postal Service built its rules around that window. Live day-old poultry must reach its destination within 72 hours of mailing, and the box must be marked with the hatch date. Flock Journey covers the history in why poultry can be shipped through the mail, including when it became legal and how the National Poultry Improvement Plan (NPIP), a federal and state program that tests breeding flocks for certain diseases, fits in.

Why there’s no food or water in the box

New keepers often ask why hatcheries don’t add a water dish. A wet chick is a cold chick. Chicks can’t regulate their own body temperature well until they feather out, and spilled water in a moving box would soak them. Staying dry and packed together keeps them warmer than any drink would help them.

Sorting, Sexing, and Counting the Chicks

Once the chicks are dry and fluffy, they are pulled from the hatcher and sorted. This is where a trained eye checks for chicks that aren’t thriving, so the ones going into boxes are the strong ones.

Sexed vs. straight run

Many chicks are sold either sexed or “straight run.” Straight run means the chicks are packed as they hatch, with no attempt to separate pullets (young females) from cockerels (young males), so you’ll usually get a mix. Sexed chicks are separated at the hatchery, either by examining the vent or, for some breeds, by feather growth or down color. Chick sexing is skilled work but not perfect, and Hoover’s Hatchery states its sexed birds are 90% accurate as to sex. That’s why experienced keepers plan for the occasional surprise rooster.

Why orders have minimums

Counting matters for more than accuracy. Chicks keep each other warm in the box, so a lone chick or a tiny group would get cold on the trip. For that reason, Hoover’s lists a minimum shipping quantity of 15 chicks, with at least 5 per sex and breed. Its guarantee page notes that shipping minimums exist to protect the birds’ health and safety during shipping.

How Baby Chicks Are Packed for the Mail

A chick shipping box looks simple, and that’s on purpose. It’s a sturdy cardboard box with ventilation holes, a bedding liner on the floor for footing, and, in larger boxes, often dividers so the chicks don’t all pile into one corner. The chicks’ own body heat is the main heat source during travel, so the number of chicks in each box is part of the packing plan, not an accident.

Season changes the math. In colder months, hatcheries generally need more chicks per box so the group can stay warm together. In warmer months, the concern flips toward overheating, so boxes can hold fewer birds and ventilation matters more.

What you might hear and see

• Peeping: a loud, steady chorus usually means warm, active chicks. A silent box is worth checking right away at the counter.
• Clumping: chicks pressed tightly together are conserving heat, which is normal in transit.
• A little mess: the bedding does its job. Some droppings on arrival are expected.

From the Hatchery to Your Post Office

Once the boxes leave the hatchery, the postal service takes over. Hoover’s Hatchery ships from Rudd, Iowa and Portales, New Mexico. According to its policies, all live bird orders ship via USPS Priority Mail on Monday through Wednesday, and most orders arrive within 72 hours. Its FAQ adds that the trip to your local post office normally takes 1 to 2 business days. The full details, including which states it ships to, are in the Hoover’s Hatchery shipping policies.

Your part of chick shipping day starts when the post office calls, because most chicks are held at your local post office for pickup rather than delivered to your door. That call often comes early in the morning. Hoover’s recommends calling your post office the week of delivery to let them know a live shipment is coming, and you can find that tip and more in the Hoover’s Hatchery FAQ.

Timing rules worth writing on the fridge

• Pick up quickly. Hoover’s policy says orders not picked up within 8 hours forfeit its 48-hour livability policy.
• Open the box at the counter if you’re unsure. Checking the chicks before you leave gives you a clear picture of how they traveled.
• Report any losses within 48 hours of arrival, as Hoover’s guarantee requires.

Flock Journey’s earlier piece on what to expect when getting chicks in the mail covers the drive home and the first hour in more detail.

How to Get Ready Before the Box Ships

The hatchery handles the hatch, the sorting, and the packing. Everything after the post office is yours, and the best chick shipping days belong to keepers who were ready a day early. Set up and run your brooder for at least 24 hours before the chicks are due, so the heat is steady and the bedding is warm when they arrive.

Your day-before checklist

1. Brooder running: heat source on and tested. A common starting point is around 90 to 95°F at chick level for the first week, dropping about 5°F per week, though your chicks’ behavior is the real thermometer. Our guide to setting up a brooder walks through it.
2. Waterer filled: room-temperature water, shallow enough that chicks can’t drown. Add marbles or pebbles to the tray if you’re unsure.
3. Feed out: chick starter in a low feeder, with a little sprinkled on a paper towel so chicks find it fast.
4. Supplements ready: many keepers add an electrolyte or vitamin supplement to the first water to help chicks recover from travel. The Baby Chick Care Kit from Hoover’s Hatchery bundles a water additive, a feed supplement, a litter treatment, and a printed care guide.
5. Phone on and loud: make sure the post office has a number you’ll actually answer early in the morning.

For a full rundown of the gear, Flock Journey’s guide to preparing for chicks to arrive pairs well with this one.

The first hour at home

Once home, take each chick out, gently dip its beak in the water so it learns where to drink, and set it under the heat. Then watch: chicks crowded under the heat are cold, and chicks pressed against the far walls are too hot. A little sleepiness after the trip is normal, and most perk up within a few hours. If you notice droppings sticking to a chick’s vent in the first days (called “pasty butt”), our guide to dealing with pasty butt in baby chicks shows how to clean it safely.

Key takeaways

• Chicks ship on the yolk they absorbed before hatching, which lasts up to about 72 hours.
• Hatcheries sort, count, and pack chicks the same day they hatch, then hand them to the mail.
• Minimum orders exist because chicks keep each other warm in the box.
• Your job starts at the post office: pick up fast, have the brooder warm, and report any losses within 48 hours.

Frequently Asked Questions

How long can baby chicks survive in the mail?

Baby chicks can usually travel for up to about 72 hours, living off the egg yolk they absorbed just before hatching. That’s why USPS requires day-old poultry to arrive within 72 hours of mailing. Most shipments arrive well inside that window, often in 1 to 3 days, but prompt pickup still matters for the chicks’ comfort and energy.

Is it cruel to ship baby chicks through the mail?

Shipping day-old chicks works with their biology rather than against it. The absorbed yolk feeds and hydrates them, and packing them together keeps them warm. Travel is still stressful, which is why hatcheries set minimum orders, use ventilated boxes, and ship early in the week, and why keepers should pick up quickly and have a warm brooder ready.

Will the post office deliver chicks to my house?

Usually not. Most live chick shipments are held at your local post office, and staff call you to come pick them up, often early in the morning. Call your post office the week your chicks are due so they know a live shipment is coming and have your correct phone number on hand.

What days of the week are chicks shipped?

Hatcheries generally ship early in the week so boxes don’t sit in a closed post office over the weekend. Hoover’s Hatchery ships live birds Monday through Wednesday, with fewer ship days in the fall and early winter. Your available ship dates depend on the breeds you order and when they are scheduled to hatch.

What should I do if a chick arrives dead or weak?

Take photos, note the number of losses, and contact the hatchery quickly. Hoover’s Hatchery asks customers to report dead-on-arrival chicks within 48 hours of delivery for a refund or replacement. For weak chicks, get them warm first, then offer water with electrolytes by gently dipping the beak, and keep a close eye on them.

Chick shipping day can feel like a leap of faith the first time. Once you understand the yolk, the box, and the timing, it becomes the most exciting phone call of your spring. Get your brooder warm, keep your phone close, and let the hatchery handle the rest.
