I have a 12 week old RIR pullet who wouldn't stand when I went into the coop to feed. I reached down to pick her up and she didn't try to get away like they always do. I put her down and she tried to stand and fell back down. Finally I did get her to stand and she walked real wobbly like she had hurt legs. I'm wondering what happened to her. I do have two roosts in the coop that are about 2 1/2 feet and 4 feet up. Normally they don't use those roosts yet but there is poop on both of them so I know they go on them some. Could she have gotten up on one of them, jumped down, and hurt her legs? Any ideas? Think she will recover, or die?
