I've got a sick hen. I recently lost one hen and now I've got another one sick. She is thin and just nibbles at food bit is drinking ok. Very lethargic and in general not doing well. I just got done treating everybody worth corid after I lost my other hen. I don't know if cocci is what killed her but she did have very runny poo. This hen is coming back from a molt and could that have caused her decline? I feed layer crumbles, they have access to oyster shell, ACV in their water and periodically garlic in water. I'm getting ready to go down and give her some sugar water to help get her energy up until I can find out what's going on.
