Hello,
I have some Marans that I got as day olds from a neighbor who has blue/cuckoo genes in the flock. I don't know which hen and which rooster produced my peeps, so don't know the exact genetics of the parent(s). All chicks appeared to be blue, not black. All 6 pullets were blue, no visible barring as adults. 4 chicks were cockerels; I culled 2. The 2 culled were a blue and one that looks like the rooster in question. The 2 kept were a blue cuckoo and this lighter one. I've read on cuckoo that a rooster homozygous for the cuckoo gene will be lighter, but having never seen one I don't know the appearance. I am guessing this guy is a homozygous cuckoo + heterozygous blue (i.e. not splash). Can someone with more knowledge/experience verify or correct my thinking? (Last pic includes the blue cuckoo rooster for comparison.) They are still regrowing after the molt. Sorry for the brassiness, my chickens free range and have access to the weather.
