I bought these as Brown Leghorns chicks several months ago. I think they have started to lay recently as I have seen them in the nest boxes but no white eggs. They are in with some of my Rhode Island Reds. All of the eggs I'm getting from that coop are brown eggs. Any idea what breed these are. The person I bought them from has moved away and I don't have a way to contact them. Their fluff is a grayish color.
