Your Barred Rock cross to your buff should give sex linked chicks at hatch with males sporting a white spot on their heads! Essentially black sex links...A little of everything at this point. RIR, buff orpingtons, americauna, red star, black astralorp, barred rock and leg horns. We have 3 silkie roosters (2 were suppose to be hens) and our big rooster is a buff orpington.
Your Easter Egger (going by spelling and other varieties kept), may give off some fun shades of "Olive egger" off spring depending on blah blah... fun to see. My EE is our favorite bird ever and she throws the cutest blue based babies
The buffs cross buff can make nice buffs... IF you like this guy.
I raised Silkies for a few years... the roosters dress well for the table. Most my large fowl hens won't squat for the bantam boys who insist on riding them like a bucking bull anyways and they would cause less peace in general. It's according to my past experiences and not taking into account personal emotion... but need that for the many "extras", the good of my entire flock and it's future including my own sanity.. I would let go (however you can) of the Silkies boys and keep the Buff... but only if he is respectful reasonably to his ladies and ALWAYS to the humans, dogs, and other animals on the pasture.
They (Silkie fellas) can also make nice pets in no hen homes, depending on the individual demeanor. If I wasn't able to re-home or send to freezer camp for whatever my reason... A stag pen with older boys too help raise the juveniles once booted from under mama or fully feathered and identified as male. Not many boys get long term free rides here... but a well mannered mature head guy to run the grow out pen can be wonderful! They break up fights, call youngsters (and the ladies on the other side of the fence) to treats, and make wonderful eye candy.
And hey if you're goofy... cross some of that Silkie in... Add some extra toes here or there... and some crests and feathered legs maybe some of that dark skin and funny comb to the mix.. and you DO get quite the variety of entertaining back yard chicken sitcoms to amuse yourself with. Seriously, sometimes very cool birds! The possibilities are endless.
Thanks for letting me in on your hatch fever.. got some brewing of my own, but birds are molting and/or juvenile. So I'm practicing the great art of patience.... for now.
