My rott-mix was "playing" with one of 9 hens pretty rough for a minute or so before my kids stopped her. The hen must have flown over our 5' fence. Its been a week and she can walk but doesn't unless forced. She is still laying eggs. She isn't eating much at all. The other hens are picking on her. IMO, the hen is in bad shape. Should I dispatch the hen? Thanks for the help.
