Not looking to argue but just want some clarification on what I've read. If the hen lays blue eggs doesn't that mean she carries two blue genes (blue coating over blue shell )? In order to lay a brown egg wouldn't the offspring have to carry a gene for a white egg? Since the gene for blue shells (from mom) is dominate over white (from dad) she should lay a green egg (brown coating over blue shell). Right or am I not understanding something correctly?
I'll just add one additional point of clarification - there is no "blue coating." Blue eggs are blue shell with no color coating. Green (or olive) are blue egg shell with brown coating.
