Last week I came out in the morning to find one of my chickens laying in the pen outside of the coop. This was early morning while the other ones were still roosting so assumed something happened over the night or the evening before (did not check them the night before and coop was open). I looked her over, one foot was bloody and appeared feathers ripped out of her back and at the tips of her wings, but she is also molting heavily so that may not be related. She is the one bird of mine that roosts low so I just assumed something came in and tried to get her. She was sitting up looking around but unable to stand and not trying. I put her in a box in the basement and have been caring for her for about a week. She is alert, eyes are bright and she is eating and drinking, but still unable to stand. When I first looked her over she reacted in pain when I would touch her one foot and leg but when inspecting her yesterday I'm able to touch and move both of her legs without any reaction. She is able to move her tail feathers so I didn't suspect a broken back. The foot does not look bad and I don't see any other injuries on her. She does flap her wings around at times if startled. Posting to the forum because I'm a little surprised I was able to move her legs around without reaction and did not see other wounds. At first I just assumed something got her and maybe she had a broken foot or leg, but now I'm concerned maybe it could be something else. I had read Marek's disease can cause a paralysis. My birds are about 1.5 years old and they are my first batch so I'm new to this. If this is just an injury, how long would it be until she was able to stand? If it was Marek's would there be other signs and would she be as alert as she seems? Any other ideas what might be going on or things I should check or watch for?
