Hello. One of my chicks has had "pasty butt" for over a week now. Every time I go to check on her her butt is caked over with poop. I have been wiping it off with warm water and applying Vaseline for lubrication (as I read in another thread). I've also tried giving her a little bit of yogurt. Her energy level is normal, she has an appetite an drinks water. She has grown some. The main concerns I have are: 1. Her butt is "pasty" everyday 2. She is half the size of the other growing chicks. This morning when I came to check on the chicks the little one's butt had some blood on it. I have seen the other chicks peck at her "pasty butt", most likely out of curiosity or hunger. The blood could be from other chicks. Should I isolate this chick to monitor her eating, drinking, and bowels? Should I be feeding her separately and/or adding to her diet? Will the "pasty butt" go away with time? Thank you for the help!
