Hello, My pekin duck who has always had great feathers recently started to loose some feathers, thought it was mites perhaps at first but they started growing back rather quickly, had similar problem with a chicken but hers she plucks and hasn't grown back nearly as much and hers has been since winter. Today I went out to the coop to do my usual routine and noticed the pekin was bleeding under his wing. Do you think it looks more like some type of infection, or another duck, or chicken, or perhaps could a rat do that? We have a rat who keeps stealing ducks eggs so I don't wanna rule anything out!!.... Feel so horrible because I feel so helpless. I washed him up and put some styptic powder on it, but is there something more I can do?? Also attached a pic of how I found one the hens the other day, all other chickens and ducks seem fine, just them two. I stood outside for a while to see if I can find a culprit but had no luck. Just want to have healthy happy little feathered friends. Thanks!! Don't want to be a bad barnyard mom !!
