I know they have different combs but at this age, they don't have combs to speak of. Is there a way to look at the beak where the comb will be and tell which kind of comb will develop? I have 5 of each and it's a mystery at the moment to me as to which one are the cochins and which are the brahmas. I know in time I'll tell but curiosity is getting the better of me! Any other things to look for? They're super cute no matter what they are!
