Combs pale with black

[Ziptydoda]

I feed my chickens (year this June 9th)organic feed, acv in water, rooster booster with probiotic, at will calcium, grit, fresh veggies, few millworms every other day or so, sunflower seeds, and free range on occasion. The temperature is 82 and breezy. They are in a mainly shaded large run and large coop at night. All are laying and act well, however they have combs that are pale here the last week. No mites one has a patch of black area. Any ideas what this could be?
Here are pictures of their combs. Thank you for your help.

Hello, thank you for asking. I wormed them and they are doing good. And yet, they still have combs that go from bright red to pale, and lil black spots come and go.
