My 5 month old Wyandotte cockerels free range during the day & put themselves to bed so I don't know if he was showing symptoms last night or not; or if he was injured somehow. When I saw him yesterday afternoon he seemed fine. He wouldn't get up this morning - I had to climb in the coop & pull him out. I gave him a once over & can't find anything wrong. His bottom does have a small amount of white droppings. I have him in a box under the garage with food & water but he won't take either. He will open his eyes and look around but that's about it. I don't see mucus. His crop is not swollen. He is very warm despite this being our first real cold snap. No sign of bumblefoot or mites or lice. I read a few threads & mixed up a molasses flush which he took easily. What else do I check for or watch for? I have Corrid, electrolytes, and probiotics on hand; should I give any of those? And what about the rest of my flock?
