Thanks for posting this. It is good information to have!!
Does it look that yellow in person? I haven't seen anything that yellow on any of mine. When my roo had something in his earlobe it looked very white.
I would say it was more tan to white than yellow. Probably just the photo. It doesn't look like this anymore, I think/hope I cured it. The other birds' combs do not look like this, it is white flaky, like when you have a sunburn and it peels. But I wonder if the Marans combs started out looking like that, I just don't remember because I wasn't keying in on it and maybe just didn't catch it early. Of all the problems to have with chickens, this is one that I sure wasn't expecting!
Thanks for the tip about the coconut oil. I will try that on dry-looking combs. I use it a lot myself in cooking.
