I have a two month old bantam Polish acting unhealthy today and I'm not sure if it is injury or disease and am looking for advice on what to keep looking for or what I could rule out. Rascal is kept on pine shavings in the coop and dirt in the run. They were just moved outside full time last week. He is with 21 other chicks the same age as him. No one else is acting different. No new birds have been added since they were all a week old. This afternoon I noticed he was a little hunched, fluffed out feathers and tail down. Normally when I open the door he is the first one to pop out to greet me, but not today. Not eating or drinking and haven't seen a poop. Just very sleepy acting but eyes open and alert at least part of the time. I thought perhaps injury because several of the more active chicks have been sparing and flying around the run. I really don't remember what he was doing this morning when I opened their yard for them. Like I said it's not much to go on, so I'm wondering what to keep looking for, what I can rule out, if anything and what I should do for him at this point when there isn't anything specific to go on. Not the best picture but my son took it and wanted it included. .
