So I have 4 Black Breasted Red Phoenix chicks. They will be 5 weeks old next Wednesday. I am really hoping for just one rooster out of this mix of 4, all 4 have the same feather pattern right now, but one of the chicks is about 3 times the size of the other 3. So my question is could this chick be a rooster and just be to young to have the different feather pattern or do I have 4 hens. Thank you!
