Sizing is the one thing worth getting right the first time. Find your chicken's breed below, or send me a photo of your bird (with something in the background for scale) plus its breed and weight, and I'll recommend a size for you.

Chickens of different breeds wearing Uni Infinity diapers in sizes Small through XL

Not sure which size?

  • Bantam chickens are usually Small or Medium. Sebright bantams and miniature silkies typically wear Small; bantam silkies typically wear Medium.
  • Rescue chickens of unknown breed around 5 lbs are usually Large. Rounder birds may need XL.
  • Standard-sized baby chicks can start in S or M, but they grow fast — most need a Large by 8–12 weeks.
  • Between two sizes? Size up. A slightly loose diaper works; a tight one doesn't. If needed, you can fold the chest bib down and pin in place to shorten the length of the diaper.

How to check the fit

  • The Uni Infinity logo on the chest fabric should sit just below your chicken's crop. If it falls between the legs, size up.
  • The poop pouch should fully cover the vent. If it doesn't, size up.
  • Straps should feel snug but not tight, resting in the shoulder joint without restricting wing movement. If even the loosest setting is too tight, strap extenders are available.

Still unsure? Email me a photo of your chicken with its breed and weight, and I'll pick the size for you. Exchanges within the USA are always free.

Frequently Asked Questions

I have a bantam chicken - what size should I order?

Bantam chickens are typically size S or M. Typically sebright bantams and miniature silkies wear size S, while bantam silkies wear size M.

I have a bantam silkie - what size should I order?

Bantam silkies typically wear size M. Refer to size chart pictures for reference. If you are still unsure, feel free to send us a photo of your chicken and we can recommend a size for you!

I have a rescue chicken (unsure of breed), who is about 5lbs - what size should I order?

If your chicken is a standard sized chicken (not a bantam), size L will typically fit. Rounder chickens might need a size XL. Refer to pictures in our size chart for reference. If you are still unsure, feel free to send us a photo and we will recommend a size for you!

I have a standard sized chick - should I order size S/M instead of L?

You could, but chicks grow quickly. Typically by 8-12 weeks, they will require a size L diaper. Refer to the pictures in the size chart for reference. If you are still unsure, send us a photo and we will help recommend the correct size!

I’m still unsure about my chicken’s size. Can you help?

Absolutely! Just email us a photo of your chicken (ideally with something in the background for scale), along with its breed and weight, and we’ll help you pick the right size.

How do I know I chose the right size?

Make sure the Uni Infinity logo on the chest fabric sits just below your chicken’s crop. If the logo falls between the legs, it’s time to size up. The straps should feel snug but not tight—if even the loosest setting is too tight, you can use strap extenders, which are available to purchase in our store. Finally, the poop pouch should fully cover the vent; if it doesn’t, get the next size up.

How do I put the diaper on correctly?

You should have received an instruction manual with your order. If you didn’t get one or have misplaced it, just reach out to us, and we’ll send you a digital copy right away.

The straps should rest comfortably in your chicken’s armpits without restricting wing movement. The Uni Infinity logo should sit low on the chest, just under the crop. Ensure the poop pouch fully covers the vent to catch all droppings.

What if the poop pouch doesn't stay in place?

If the poop pouch shifts, secure the straps together just above the tail using a small clip or paper clip. This helps keep the pouch properly positioned and ensures it catches all droppings.
