My Jersey Giant (black) cockerel has been giving my White Leghorn girls a workout the last couple days. One has been laying a couple weeks and the other started yesterday. One egg had a break in it today so I cracked it and it was fertile! Go figure. I don't have plans to hatch any of the Jersey cross babies as I really did not expect him to actually "make it work" with these smaller girls. But apparently he did! What the heck would a JG/WL cross look like? A really big egg laying machine? A really small poor layer? Sort of related, can some explain the white gene that is White Leghorn? Is it dominant or recessive? If so, how does it carry up against a blue (andalusian) or red (RIR)?
