I have several hatchery chicks from MPC. I am still trying to determine Welsummer versus Brown Leghorn. When do ear lobes develop their "color" and size that I would be able to determine this. Also, if a Brown Leghorn do they get early comb development? I have a few with bigger combs and one which is very slightly pink. I know I have one Roo out of 25, I am questioning 2 more. If one is a Wyandotte, I'm safe, but if not I'm doomed or it's doomed to freezer camp.
