I found my Cochin Rooster, 1 yr old, looking like a sack of feathers. For a week I held him and fed him eyedroppers of duramycin treated water, crushed chicken meal in weak milk, and sometimes some cream of wheat in milk. I kept him apart in a carrier, with water and food available, but he just laid his head down and was very lethargic. I also saw some mites, so dusted lightly with Sevin. But after a week he got perkier, and started eating and drinking some on his own. He is back to his old self, crowing and strutting for his girls. But what happened? I didn't want to lose him, as he is a great Daddy and protective roo. Any insights?
