I put a pinless peeper on an aggressive hen about 25 days ago and it certainly has helped for feather picking but now I see I big lump on the area of her beak that's between the nostrils and black color around the area where the prongs go in (I thought this was dirt but now I don't know). The nostrils look a little wet too (clear liquid). I don't see any blood. Does this sound like an infection? If so, I'd like to remove the peeper! Thanks for any help!
