I have a wonderful assortment of chicks, some a month old and others a week younger. I have two roos (STILL not feathered except wings and very upright). I also have a few that are going very red in the face, but are fully feathered. Heres the thing-a few are sexlinks (so DUH theyre pullets). Can brighter combs and wattles be a sign of health as well, since my red and gold sexlinks are showing much redder faces?
