I've had leg issues with this chick before and I thought they were getting better. He was standing and walking with only a slight limp, but when I checked on him today and he won't even stand on it. He is on pine shavings, so slipping shouldn't be an issue. He's about 6 weeks old and his other issues were when he was about 3 weeks. It seems to be just one leg that the toes are now starting to curl up on (which is a new issue). It also looks like his hocks go in instead of straight. How can I try and fix this issue. I feel terrible for him now because he won't even stand up and walk! Any help would be great!
