I have 4 white leghorns 2 buff orpingtons and 1 partridge rock. I am getting white light brown and dark brown. I read the the leghorns are whit but when i actually seen her lay a light brown i was confused. I done some searching on the net and on the BYC and found i could have white rocks. I have read if a chicken has red earlobes the will lay brown and if they have white earlobes they lay white eggs. I am go8ng to try to post picks of them. Can anyone give me advice?
