I was out this morning and saw black spots on my buff orpington's comb, wattles and earlobe. Is she getting a disease or is it too hot for her?
Black spots on chicken's comb, wattles, and earlobe
On mine, I had dark spots on the comb and attributed that to watermelon juice that got dirty and dried. Trying wiping it off with a cloth.
I am assuming it is not cold where you are.
A couple of my hens got this. It wasn't a bad case. Just small black spots on the comb, and a few on the wattles. It started with my white leghorn. I used some grapefruit seed extract on it, and then oregano oil. I put it in their water, and some diluted in olive oil directly on the spots. Two other hens had it(I have 8 chickens in all) the same. It seemed to run it's course quickly(1 week)and never progressed to anything worse. I read that once they get it, they won't get it again. I didn't notice it on all of them so I am hoping the oregano oil in the water kept the others from getting it. Oregano oil and grapefruit seed extract are natural antibiotics.
