HELP! So i'ts winter and I put my chickens in this little coop. I think it's a small place for 21 chickens but my dad says it's enough space for them. Well my dad noticed that our Rooster hasn't been walking right. So we leave him outside of the coop for a day and he does walk but he walks weird. It looks like if he was hunchback or something. I think it's his spur cause it is really, really big but my dad says it isn't. Can you guys please help?!
