They are going to be 4 weeks old in 4 days and I really would like to know sex. Ana is bigger, heavier, has thicker legs, bigger redder comb, and stands up really straight when frightened. I think Ana is a boy, but I just want to make sure. I think both Ana and Elsa have some Ameraucana in them. Here's Ana. And here's Elsa. She's smaller, lighter, has a smaller comb with no red and has saller legs (i think). A good shot of her beard. Them together. Do you notice any difference in their legs?
