Hen hatched 6 chicks on March 2nd and I know for sure two are roos as I have heard and watched them crow. But the other four haven't crowed. What does this one look to be? hen or roo? What about the first chick in the second picture the one that looks to be part silkie does it look like a hen maybe? The chick in the middle of the second picture if the same chick in the first picture. We all know which one in the second picture is a ROO for sure.
