hey all today I discovered one of our baby chicks had pasty butt. i’ve dealt with pasty butt before and did the same thing i always did which was hold luke warm watered down paper towel down to it. after i got it off i put her back in the brooder. the others chicks wouldn’t stop chasing her down and picking at her butt. (she’s also the smallest out of the bunch) i then noticed something pink was hanging out of her butt!!! I’ve seen her poop twice and eat and drink. for now i’m just watching her to make sure the other chicks don’t pick at her. what is it and what should i do?
