My flock was out free-ranging this afternoon when we noticed we hadn't seen Tiny in a while. Tiny is an Old English Game bantam roo who is 4 1/2 months old. He typically follows around Reggie who is the booted bantam he's grown up with. My husband found him lying down behind the coop. He seems to be breathing okay, no obvious injuries. His comb doesn't look quite as red as usual, his tail is droopy and he hasn't made a sound since we found him; usually he's constantly muttering to himself. Not sure about his poop as he's been in with the others. However, I cleaned out the coop today and didn't see anything unusual. I've moved him into the house with a towel to rest on, pine shavings in the box as well. He has layer crumbles and water. At the moment he's just standing and sleeping. What else should I be doing? Any guesses as to what's wrong/things I should check? This is our first sick bird ANY help would be GREATLY appreciated!
