My BPR chick has been having pasty butt issues. The other chick was pecking at her vent so I separated them with hardware cloth and have been cleaning the chick's butt by soaking in warm water and removing the poo. My question is that her vent is really large and distended. Is this normal? She seems to really strain when pooping. Is she constipated? Here's a pic. Her vent sticks out farther than her little tail. Any information would be appreciated. Thanks.
