It's a tough thing to deal with. Sorry about your hen. I've not tried it with a grown bird. My boy is still growing, and the more he grows the better his leg looks.I quoted myself from another thread to get all the info over.
She is quite the escape artist. (In part how she got her name.) I have her hobbled again with the vet wrap. I feel like if I could get her leg to stay back, even if it were stiff it would be a more functioning leg.
How has it been going with your bird?
