Although the diapers are machine washable, we recommend hand washing to maintain fabric quality and extend the life of your diaper.
Tips
- The diaper should sit low on the duck's chest.
- The poop pouch should be positioned directly under the tail.
- If the diaper feels too long, fold and pin the front portion down for a better fit.
- If the straps are not long enough, strap extenders are available as an add-on in our store. Please check your buckle type to ensure compatibility before purchasing.

I love it! It works great as you can see, and it has a waterproof liner, so I just dump the poop/toilet paper in the toilet, rinse it off, and she's clean. I used Velcro at the crisscross because the runners stand tall. As long as it's Velcroed between her wings, it stays on, and she's happy. She has free range in the house for now, and it's a lifesaver. My girl is 5 weeks old, and this is a medium, and it still has some room, so it should be fine. I put her tail all the way in the sock because I don't see how it would work otherwise, but I just wash her butt when we take it off, and we're good.
These are fantastic for baby geese and I'm sure ducks. I love the wide pouch so it fits well. It took us about a day of on and off until she got comfortable with it. The adjustable straps are great to have also, they grow fast!!!
Perfect. You can tell it’s made well and with care. Worked perfectly for my little faverol (probably spelled that wrong) Trish.
I found this product to be comfortable for chickens. Good quality, fit and price! Highly recommend!
Super cute! Absolutely love it! Bought a slightly bigger one for when my chicken gets a little older too!
Frequently Asked Questions
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.
