I have a single gold Sebright hen, "Salvadora" that came as my "free, rare, exotic chick" from Murray McMurray. She hatched about April 26th of this year. Her comb has turned blue-black over the last month or so. I see in googling that some silver specimines have dark combs. Is this something I should be worried about??? She is otherwise perky, flies up to my arm for treats, follows us around like a dog etc. She's a smart girl who is usually found rosting under the cochins for extra warmth when it's cold so I'm not thinking it's frostbite. Additionally, we'd love to know if her bold personality is typical of the breed. If so we're thinking of expanding our flock!
