I got 2 Light Brahmas and 2 Buff O. yesterday (all pullets). They are between 4 & 6 months old. A couple of them have some really bad diarrhea. (no blood) I gave them some plain yogurt last night, what else can they have to help the digestive tract? I plan on worming them, and giving them a bath at some point ~ they really stink bad. Thanks!
