Hi, I have read posts about "pasty butt", but I am not sure that is what I am seeing. My chicks get ROCK hard feces stuck to their fluff. I am cleaning it off, but I would like to know what is causing this. The chicks I raised last year, never had this sort of problem. The only difference in what I am doing is this time my feed is totally mashed (it looks like ground up graham cracker), whereas the first time, the feed was in "crumble" form. Do you think this is the issue? Also, I keep a heat lamp on 24/7, and in my house the thermostat is usaully in the mid seventies. Is this okay? They aren't panting, and if I turn the lamp off, the tiny chick, Cookie, seems cold. She'll just stand there and do nothing.
