My daughter was moving a pen around in the backyard with the chickens in it. One of the chickens got its foot stuck under it and may have injured its toes. We have tried to take pictures, but couldn't get a good one flat on the ground. It is the inside toe on both feet. It doesn't appear to be in any pain, but the toes bend back/twists at the joint. Our chicks are only 6 weeks old, but we haven't noticed it before. These are our first chickens, is this normal or did something break? If broken, is there anything we can do?
