So I have two White Leghorn (F) x Black Copper Maran (M). One of them has been growing a comb since he was 2 weeks old and the other one barely has one. I was talking to my neighbour (who I got the chicks from) and she said that the comb size can be misleading when sexing leghorns. Just wondering what you all might think on the subject. I also have a chick from her that is either a purebred Copper Maran or a Copper Maran x EE. Any thoughts on him? Thanks all!
