I hate to say it.but this little one might be a little too big now to fix the issue
Over the summer I hatched a barred rock ..Norman who had splayed leg, I did the hobble on him, it worked kind of for a short while, but then his toes curled to the side his hip started bowing out, I brought him to the vet and his tried the hobble too, but it got worse and worse to the point where his joints were getting really warm and he pretty much couldn't walk anymore.
I made a tough decision to have the vet put him sleep as he did not have a good quality of life, he was only 4 months old and so sweet
I hope someone has some suggestions
