I have a chick with what appears to be a grey comb. It is one of the 4 that I hatched from my chickens. I believe, from the breeds I have and the egg color, that it was a cross between my Blue Andalusian roo and my Black Australorp hen. I have never seen such a thing before---curious if anyone knows if it will remain that color or change as the chick gets older (about 5 weeks now).
Here's a pic--- hope it is clear enough
