I've got 4 backyard hens. They are banties ranging from black to grey. The grey lays almost white eggs and the other three lay light brown. All are the same age (about 1 year), from same batch, live in the same coop at night, range in the same backyard, etc. Three of them have some BLACK SPOTS ON THEIR COMBS AND WATTLES. It looks a little fungusy, raised a little off the natural red. The largest spots are the size of the end of my pinky and they go down in size from there. We haven't noticed any other symptoms. Is this some kind of fungus, disease, deficiency? I'd appreciate any help on this matter. My children treat these chickens like pets and are handling them througout the day. Obviously, I need to identify this thing! Oh yeah, one of the three is keeping one of her eyes closed a lot throughout the day. Thought I'd mention it in case it was related. If not, help me with that, too!
