Two of my chicks, they are RIR's, have loose stools, and one of them is laying down in the bottom of the brooder, and kicking it's legs back behind him...almost like it's trying to gather the pine shavings up around it in the form of a nest. Then while he's doing that the other ones peck on him a little. It doesn't act like it's sick, just like it wants to sleep and make a comfortable spot. I'm worried about it though, b/c the bottom of the brooder is slippery plastic, and I'm afraid that he'll hurt his feet...that paranoia comes after reading some posts on here about the lame chicks and splayed foot condition. Am I worrying too much? Are these things normal?
