Hi I am a first chick raiser/ owner and we got six chicks at two days old about five days ago. They are in a brooder in a bathroom and we have checked the temperature often. Two of our chicks had "pasty butt" and we noticed it the second evening we had them.. I cleaned the pasty butt as I was instructed by different websites. I even fed them a little plain yogurt in their feed to help with the pasty butt. One of the chicks that had pasty butt has not grown and is still much smaller than the other birds are at a week old. She chirps constantly and will NOT LAY DOWN to sleep at all.. Se tries to sleep standing up but wobbles and wakes up. I don't know what's wrong! I thought maybe I hurt her by cleaning her butt but the other one with the pasty butt is fine! Any ideas? She seems to be eating and drinking but is not growing or sleeping!
