A Detailed Explanation of Pasty Butt in Chickens

Pasty butt has several different names that are common. It is also often referred to as pasted butt or pasted up. Mostly, pasty butt occurs in young chicks when their poop becomes hard and covers their butts. This blocks additional waste from making a clean exit and eventually can poison the chick. Chicks need to rid their bodies of waste. If they can’t do it, the waste will begin to spread internally and could eventually kill them.

Why Do Chicks Get Pasty Butt?

Pasty butt is far more common in chicks that are separated from their brood. This, in turn, causes the chicks to be stressed and become too warm. Overheated chicks need someone to clean them since they can’t do this themselves.

Alternatively, chicks can get pasty but from being too cold. Finally, It is far rarer, but some viral and bacterial infections can also cause pasty butt.

If your chicks hatched naturally and are still a part of the brood, you likely will not have to deal with a pasty butt. And, if a chick in a brood does by chance get pasty but, the mother hen will take charge and clean the chick.

Chicks cannot clean themselves. If you ordered them through the mail and they have pasty butts, it will be up to you to clean them.
