I have two white leghorns and two RIR, both my leghorns have a pale beak while my RIR's have orange beaks. One of my leg horn has a black line on her beak that reaches her other side of her beak. It sort of reminds me of a bruise but not sure, noticed this about a week ago. Another question, my chicks are two weeks old and my leghorns are starting to develop a comb, I can only see them if I squint and see the ridges. Are these early signs of a rooster? my two RIR's don't have this yet.
