I have a barred rock that has a yellow/greenish diarrhea. She seems to always have had it. I have had her since September. When I got her I knew she was too young to be laying. But, recently her comb has turned red and she has gotten more vocal. I have been expecting an egg, but was thinking that maybe it was her diarrhea that was keeping her from doing this. The people at the feed store here have no knowledge about chickens, so they have been unable to really help me out. She is eating laying crumbles, scratch, and occaional treats like lettuce. Any suggestions?
