My 4 week old baby chick has started limping. I noticed earlier today he was laying in a corner and didn't want to get up. When he did he kinda wobbled and sat back down. I went to check on him just a little bit ago and noticed that he doesn't want to put weight on his leg. His toes aren't curled but he is in pain because when I tried to see if there was any physical injuries he kept peeping and pulled his leg closer to him. I've read that it might be a slipped tendon but I'm not sure. If it is what's the best way to help the poor guy. He only wants to sit down in the corner of the brooder.
