Coo-coo is my all time favorite hen! My only coo-coo Moran. She's sick. Lathargic. Hardly moving around. Tonight too sick to get up with the others to roost. She has diarea. Her backside is stained with runny poop. I've seen this happen before with her, but this time she seems really sick. I cleaned her up and put her in a separate pen alone. If she makes it thru the night I plan to give here lots of corn and the laying mash pellets. My wife suggested a banana for diarea. Maybe yogert. Any suggestions?
