the 2 are pretty much the same size, combs are coming in nicely. Then there's the other, 'he's' bigger with a more round plump rectangle shaped body. He tends to venture away from the 'herd'. I believe he's a rooster and the others are hens. theyre a month and a half old so i should be able to figure out genders soon right? is it safe to assume I have 2 hens and a roo? these are my first Giants <3
