white spots on comb

[HerbDoll]

We had a veterinary appointment for a horse, so just took the chicken with us because we needed to know if it was infections due to an upcoming show. My daughter has been excited all winter/spring to take 4 chickens to the 4-H Fair, and so we didn't want to just "wait and see," and either be in quarantine or make other kids' chickens sick.

The vet thought it looked like a sebaceous excretion, but it was really "attached" and wouldn't come off easily. He got a scalpel and took a scraping to look at under the microscope. After looking, he still felt it was sebaceous and not parasitic.

He thinks that this chicken metabolized the dewormer differently than the other chickens, as she had been dewormed 2 days before onset. We knew that the other examples we had seen that looked like this also happened to be EE/Ameraucanas (pea combed chickens). So, possibly these chickens are a little different in how they metabolize dewormers from the Fenbendazole/Albendazole family. It would be interesting to know whether the other chickens we've seen pictures of with this had been recently dewormed with that.

So, we will see if it goes away in a few days when she has finished metabilizing the dewormer. He suggested putting mineral oil on her comb to see if it helps us scrape off the crud by softening it.

I know this original post was years ago, but my rose comb wyandotte has this exact same too, only worse. Did you ever find out what it is? Seems there's not enough info on this exact looking white spots.

NOT dry fowl pox. Different composition. Almost like calcium deposits. I thought she may have taken excessive amounts of oyster shell but the fact that mine responded to antifungal ointment proved it was a fungus. Maybe a ringworm/favus.

Sorry to bump an old thread, but I found this quite interesting. My EE also has similar spots on her comb and her eggs consistently have calcium bumps on them as well.

My EE has had these bumps for about a year, now, and they don't really change or improve with any kind of treatment. I've tried to moisturize it with vaseline, I've tried antifungals, nothing. It doesn't worsen and it doesn't really bother her, so I figure it's what the others have said in this thread and it's just a weird sebaceous excretion.
