Okay, I looked at all the references for the moldy feed in The Chicken Health Handbook, but I couldn't find anything with symptoms related to paralysis (or curled feet, like my roo)...?? I suppose this could still be a problem. I didn't think about looking up "paralysis"--thanks for that...
Did you find out anything about the moldy food possibility? I have posted about a similar problem with my almost-1-year-old Marans roo. He is perky, eating, drinking, etc., but feet are curled up. He scoots around on them a little bit, but basically just rests on his hocks....It has been raining...
