My 3.5 year old, non-laying hen, a Buff Orphington had/has diarrhea--white, green, yellow color-- but acted fairly normal but went down hill over a three week period. Due to the very rainy weather, I figured that perhaps she had eaten a bit of moldy food or was effected by all the damp stuff in the chicken pen. I started giving her shots of Talon, plain yogurt along with some healthy vegetables. One day she would seem better walking slowly and interacting with the other chickens, and then she would be sicker the next day. Currently, the back of her comb is bluish, her tail is hanging down. Her belly to the vent are as hard as a rock. She is extremely weak. I thought she might have Ascites. I read and watched the videos. I tried to drain her , but nothing came out. She and I are sitting here wondering what can we do to help her feel better. Your advice is welcome.
