Hi friends! I'm a relatively new chicken owner and I thought I had female EEs... Up until very recently when they started crowing regularly. I was living in denial about one and was shocked when I physically saw the other crow. I'm still not 100% certain on the other. Can anyone help make that determination?
These are the two in question. I'm certain the one with white tailfeathers is a roo, the one with gray tailfeathers is the one I'm not 100% about. They are both about six months old, hatched some time in May. I brought them home on Father's Day.
Here's a couple more pictures:
Thanks in advance for your input, though I'm afraid I already know the answer!
