3 days ago I put 2 chicks and 2 poults out in a larger brooder on the porch. They are about 2 weeks old. It has pine chips on the floor. Yesterday morning I noticed that he couldn't walk very well. He is balancing with his wings and hobbling with his other foot. His elbow(where fuzziness meets flesh is a little swollen compared to the other. He's eating and drinking very well. I brought in a 4x4 inch plastic pot, put a few pine chips in it and he loves nestling in it compared to being used as a bowling pin for the other 3. I take him out every couple of hours and he eats and drinks normally, pooping normally, and I put him back in his pot and he's good. He's very alert, eyes open wide. He doesn't appear to be in any pain, but he must be. When I first noticed it, the foot was twitching but has now stopped. The toes/foot, he holds together as opposed to stretched out for walking and he's holding his whole leg up under him but can stretch it. Has anyone experienced this? Should I just put him down? I sold a bunch of poults this year but was going to keep these last 2 just for myself. Any advice? Thanks
