I have saved every chick that I have hatched from my one and only green egg laying Naked Neck hen.
I don't think she is capable of producing a female chick. This last hatch of September 22. I hatched three chicks out if I think it was seven eggs. Two weeks ago I culled one of them because it was a definite make.
Today I went to get the other two, what I thought were pullets, look I think it is two more cockerels.
I don't know if it had anything to do with the hens mother having spurs or not.
I will try one more time to see if I can't get at least one pullet from her. She's going on four years now. I think this coming May.
This dark one looks like hen to me
