I recently lost a pullet to cocci, and so I'm a bit on edge. I know it's rare in adult chickens, but can anyone tell me the warning signs? One of my hens, an Ameracauna, was moving a little slow today at times, and I saw her sort of "zoning out", laying down, and letting her eyes drift shut in a sort of weird way. It's very possible I'm overreacting, but I thought I should ask to be safe. Any thoughts?
