For the first time in 2 years a blankety blank dog came into my yard and attacked my flock. Killed a rooster and injured two ducks. The one duck seems to have a leg injury. He will move his toes but won't use his leg. I've got him confined and comfortable right now. I've read on this site about bath therapy, but should I try that now or let him rest a day or two before he tries to use it?
