I have 3 and figure I know the sex for 2 of them. They are all 5 weeks old. The first chick I am sure must be a roo. The 2nd I am sure is a pullet. But the 3rd's comb is smaller then the roo's and bigger than the pullet's. Maybe a slow roo? Any ideas??? TY!!! BTW, I know the pics are poor but you can see the combs well enough to tell I think.
