Comb partially changed from red to yellow in 5 month pullet

[mamamutt]

I am fairly new at this chicken business! Please forgive and correct anything I get wrong. I have 5 pullets that are 5 months old. One just started laying this week! YAY! However, her Coop-mate I just noticed has a little change to the top (back?) of her comb. About 1/3 of it is yellow. I am kind of stumped.

They are on hatch to hen feed currently. I just began mixing in layer feed today. I did give them a cabbage head as a treat this week for the first time. That was fun. At least for me

They are in a covered run so no new environmental stuff that I can think of. She is perky and excited when I come to the fence. I have ACV/oregano/electrolytes that I can and probably will add to the water today just in case she just needs a boost.

I'll be honest I don't quite know what to look for in terms of skin issues/mites etc. Am I anywhere close to helping her? Missing anything obvious?

I'm grateful for any input at all!

Do you have a picture of the comb? Is it cold enough for frostbite where you live? It would be helpfulmto take a look at what you are seeing to give advice.

I didn't think it was cold enough for frostbite, but I can't rule it out. They have been out during much cooler nights and didn't have any effects.

I had also forgotten she was my chick with the white on her earlobes. Related or is that just her?

It is possible that it is just a touch of frostbite or an injury that is healing, but the comb is hard to see in the pictures. The pic below shows some of the color changes as frostbite heals.

I sincerely appreciate the input. Nearly everything I read hinted that frostbite would be darker vs lighter. I had no idea that this could happen even in the 30s. The temps months ago had been in the teens. And as I typed that I just realized they didn't have their big girl combs then! So much to keep in mind and learn. Thank you very much!

I don't really see anything on that birds comb.

Nearly everything I read hinted that frostbite would be darker vs lighter.

Mild frostbite can be grayish, severe frostbite goes black, black tissue will slough off.
Medium and healing frostbite can be yellowish like @Eggcessive showed.
