My Copper maran has feathers legs, and for the 3 weeks I have owned him, he seems to have shakey legs, he is the same size as the hens, but he has been with us three weeks and the shaking like he is scared hasn't gone completely away. he is about 3 months old. he seems to have strong legs when I pick him up and when I am not watching him. Today it was hot and humid and he and the 4 hens he is with were panting, but not one of the other breeds seemed to be as hot. I put a fan near them and until after it rained they panted. Is that a worry?
