Wild type is the base under most colors, slate are black base, black is dominant so she must have one black one bronze gene covered by the black. Black birds can carry bronzeMy blue slate hen brought home a clutch of gray poults and black poults (as expected), but also a bronze poult. I have been experimenting with Porters turkey calculator to figure out who the father could be, but there is no color combo that could make bronze. Is wild-type a random mutation that can show up sometimes?
