I heard a strange crowing this morning unlike any of my roosters - 4 bantys and one a bit bigger. This sounded like a much larger bird, with a very deep voice crowing. I went out to the back yard and waited and it was one of my 2 dominecker hens, or at least I was told was a hen. He (she) is much larger than the other one and is the biggest chicken I have. He (she) has shown no male behavior and gets along with the other roosters well. So my question is now.........is this a hen or a rooster? She is about 5 months old so I think too young to lay eggs yet. The other dominecker has not started to lay either. Is there a facial feature that would give her sex away?
