@BlueTheBrahma
it is rainning today so I have a time to do some internet work .
here the method to breed a new strain of Golden cuckoo marans from crossing a BCM to English Silver cuckoo ;
Year 1 :you have a trio of BCM french type ,you need to find English silver cuckoo marans trio .
first mating: pen the BCM rooster to the 2 Silver cuckoos hens = hatch F1 a DZ chicks from each hen . this F1 progeny will be all E/ER
all cockerels will be S/s+ . B/b+ dark split golden cuckoos ,
all the pullets will be s+/- BC .we keep the best few cockerels and few pullets ( dark eggs layer )
do a same thing with a ESC rooster mate him to the 2 BCM hens = hatch F1 DZ chicks from each hen. this progeny will be different all E/ER . all dark cuckoos .S/s+ .B/b+ for cuckerels and S/- B/- for pullets unpure silver cuckoos ( carriers of the Autossomal red genes ). select few nice cockerels and few nice dark eggs layer pullets.
this is end of year one ,
