I got 5 SEE
View attachment 3529317from TSC, too, last month. I think Coconut is a rooster! Here is a photo of my 5 (theyre in quarantine right now), and of my Roo Boy.
Aloha, I got 3 SGE's from TSC last month, and 1 is a rooster. What if I breed them together? I know Hybrids do not breed true, but I don't hear anyone asking, what if we breed the SGE's together? Will we get more or maybe a 50/50 split of SGE's, or will we get Praire Blues and whatever brown egg layer Hoover's used? Thanks!
So, I'm no expert, but what I do know definitely won't happen is reverting back to whatever they use to make the hybrid, or to Prairie Bluebell Eggers, because I'm sure that's not how they are bred. But, IF your cockerel has the blue and brown genes, and you were to breed him back over the green laying SGEs, you should have a chance at blue, green, and brown eggs, possibly 25/50/25, but that's only a guess. IF he's carrying blue/tan genes, you would stand a better chance putting him over a "true blue" hen, or vice versa, a Welsummer or "true blue" rooster over the green laying hens, but if you put him over a true blue, those chicks should all carry blue - some laying blue, and some laying green. Or you could test him over the Welsummers and hypothetically you would know IF he's carrying blue because half should lay olive speckles, and half would lay brown speckles. I have no idea how many chicks you would have to hatch out (and grow out, and wait for them to lay) before you knew if your experiment had worked.
So if you are someone who doesn't mind to wait and see what you get, and doesn't mind having more brown layers in the mix, it would be fine to try! But if you are looking for more predictable colored layers, there are definitely more straightforward ways to go about it.
On a side note, even blue layers at times can carry recessive white, so you would need to know you were using a "true blue" bird to get blue and greens, otherwise bB x bw would get you the mix of blue bb, blue bw, green bB, and brown Bw but you would have no way of knowing which blue layers were still carrying the recessive white and which were true blue. Vs. bB x bb gets you only blue bb and green bB.
ETA Personally, I would maybe stand a better chance of putting him with my Welsummer hens to get some olive eggers. But they would definitely not all lay olive, and there's a chance none would.

The ones who lay brown should still have speckles, but wouldn't be Welsummers anymore, so it would remain to be seen how useful they might be, to still put with a blue, or cross back with the SGE daddy rooster and maybe get another 50/50 chance of getting green speckles again. All for funzies lol
EATA Already I might see a correction based on this chart below, because it says they always pass on the overlay, as in a green and a green will not ever get back to blue... :/
