My Red Sexlink started limping. Some of my other chickens have limped before, and it eventually went away. I noticed it looks like her toe is crooked, and does have some swelling into it. Her hips seem to move freely, but she does seem bothered by me messing with her foot. It did not look like anything was in it. Here are some pictures I can get a picture of the bottom of the foot, nothing looked out of the ordinary. I have her half a baby tylenol. and let her go on her way. I do know that they jump off the top of their coop and try and "fly" as long as they can, and sometimes off the deck if they can.
