My 14 week old pullet has started limping rather heavily, favoring her right leg. I've inspected her multiple times and can't find any injury, signs of bumblefoot, or even any swelling/discoloration. I thought perhaps she hurt it flying down from the roost (it's 4ft high, but they have a thick layer of pine shavings and it's in a large coop) so I made a ramp, but I can't say I've seen her use it... Is there anything I can do? Is this a wait and see kind of thing? I was thinking about putting her in a dog crate in the coop for a few days to force her to rest. Would this help at all?
