Hi, I noticed on one of my hens yesterday that her wattle on one side is inflamed. Please see photo. It looks like some kind of "hole" / scare from piercing or infection of a bite on the outer side of the wattle combined with swelling (see second photo). She is perfectly fine in terms of eating etc and she is certainly not impressed at being put a coop. She is in the coop so i can separate her from the flock and give antibiotics.
I would be truly grateful if anyone can suggest what the problem might be and what i should do about it.
