I have black Jersey Giants and it appears two have gotten red on their combs but I'm not sure if maybe the one is just plder than the rest by a little?
They should be about 7 weeks. I'm going to post all 4 of them (2 I'm fairly sure are pullets and 2 I'm not sure. I was sold all pullets but you know how it goes) and if you need more pics let me know! Im hoping the more white face one is a pullet... This one was always a bit bigger than the rest since I got them. And they're all hatchery stock if that matters.
