HELP! One of our chickens approx 21 wks is having problems walking. Right leg seems to give out from under him. Noticed a little irritation inbetween toes so put neosporin on it. Put her in a crate in the coop to keep him calm. He will still get up and the leg seems to go out from under him. Is this all coming from a little sore spot inbetween toes or is this a bigger issue? What should I do. New to chickens and looking for any advice I can get. thanks!
