Theory one says you can sex them at day olds by the stripe on their head and chocolate color on the back. If that is true than 1 and 2 are girls and 3 is a maybe. Theory two, according to Mother goose, she can tell by their combs at week olds. These little ones were hatched 1/31. But there is virtually no difference in comb. That means they are either all boys or all girls. All girls are great, all boys and I will cry myself to sleep tonight!! So which are they???
