Hi, I recently got a Silver Spangled Hamburg chick from McMurray hatchery. I think he is a roo because that is all they had available for that shipment, so I would guess that they gave away the extra males they had left. I also have Black Australorps, some Red and Black stars for egg layers, and some Pioneers for meat. Has anyone tried crossing these breed with a Silver Spangled Hamburg? Any thoughts on whether they would make good hybrids?
