I have a hen that is an 11 month old Barred Rock. I am pretty sure she got her leg run over by the car today. It just hangs limp and she obviously can't walk on it. Is there anything I can do for her? Or will she need to go in the freezer? If there is no hope for recovery then I don't want her to suffer, but if she has a chance to heal I would like to try to help her. She is a young, very nice hen. Thank you!
