I have recently adopted two beautiful but neglected bantam hens from someone that was too old to look after them anymore. Their legs and feet are stiff and swollen and look dirty. Their previous owner said that it was an injury from tripping over some baling twine, but I am worried that they may have a disease that could be passed on to my darling rooster. One of them is still very young and has recently hatched her first offspring. She is very skinny and her head hangs down sometimes and her comb is very small. Her vent looks a bit poopy. The older one hardly ever uses her left leg. Her comb has some rough black markings, which the owner put down to fighting/pecking. I was told to dip their feet in used motor oil, but I dont trust the idea. I would love to keep them and nurse them, but not at the risk of the other poultry. Please help!!
