Offspring hatched from dark eggs. I only hatched the darkest colored ones on the right. This is a sample of all my colored eggs, but shows her darkness in those 2:

Hi Morbius18 I see you done a good job with your golden cuckoo rooster.I m impressed. I ll do the same if i had him.
Now you have too route to take to create 2 line from him.
option 1) put him over his daughters to create an F2. ;line A
option 2) cross the F1 to the F1 to get the F2 B. you will have a nice pure golden cuckoo coming out of this cross ;line B
Olive eggers I don t know much about them
good job and Bravo
That normal the F1 cockerel is a single dose B/b+ like his sisters they are also B/b+.
with 2 pullets ( your are nice ) you can do both option; mate them first with they sire make a few chicks and swap the rooster and put the cockerel ( they brother ) over them and catch few chicks from them Line B.
in the F2 generation you will have a DF ( double factor B/B ) cockerels.from both option
F1 X F1 mating is a good way to know what your parent stock birds are . witch genetic family .ER. EWh .e+ etc......
by crossing the F1 between them selves you get the chance to see the recessive genes and breed them out.
when we don t do that and we cross the progeny back to they parent stock ,we ll never know the recessive genes and they will be passed down to they progeny.that what caused different colour chicks come out some times from an established pure line.
in your case if your rooster is ER/ER.,than the F1 crossed between them selves will give this result. 25% each; - Golden Cuckoo pullets. - Golden cuckoo cockerels DF. -Golden cuckoo Dark cockerels and Black copper pullets.
if he isn t than you will know what are you breeding
Here what happen to me with a Birchen marans.
my friend he bough a birchen hen. exellent type egg color 5 at her best.
he cross t with a BCM rooster egg color 4( work in progress ) he got the F1 only one birchen cockerel ( impure S/s+ Gold/Silver ) the rest BCM .
next year he crossed the birchen cockerel back over his mam = he got the F2 all the pullets 8 where Birchen but the cockerel where impure Golden/silver but one of them was a pure silver.
He passed his chooks to me to work with them and develop them.
last year I crossed this F2 pullets and 2 of thet brothers together = F3 here what I got .50% Birchen. both sexes . 25% Black copper only pullets. 12.5% Golden duckwing( salmon type chick) and 12.5% silver Duckwing.
you see my friend where the duckwing ( wild type) chicks come from . the Black coppers where expected but NOT the a Salmon.
now this F3 Birchen are more pure and can be bred as a pure strain. maybe one more crossing in the future I want to make sure no recessive genes is left there.
So it important that when we make a crosses we have to cross the F1 generation between them selves.
