A combo pack of those would be fun! I don't know nearly enough about sex linked chickens. Had no idea anyone had them laying blue. They sound great!
"Sex linked" is a genetic formula to make the chicks sexable by down color (or feather growth), it doesn't define the egg color, but you could think that, since no hatchery sells sexlinks that lay any color than brown. I create blue egg sexlinks several years ago because I love the black ameraucanas, but was frustrated at how long it too to determine the sex. The "Blue Egg Black Sexlinks" (as I named them) are easily sexable and the hens look almost identical to a black Ameraucana hen, except they lay a *lot* better!
I think I understand why, did some more reading on F1, F2 etc. Still sounds like a great breed to own and worth having.
They are not intended to be a new breed to use for future generations. I raise the parent breeds and make the cross each year, just like hatcheries do. For predictable progeny that lay lots of blue eggs, you will not do better than Cream Legbars, but if you just want a prolific blue egg layer and don't care about the future generations, either blue egg hybrid works great. My other hybrid, that I call a Zebrina, is a black barred, crested blue egg layer -- a cross of Cream Legbars and California Greys. This is my first year selling them, but I absolutely expect them to be the best ever blue egg layers, and completely unique looking. The Blue Egg Black Sexlinks look like black Ams, these resemble the Cali Greys, but the crest and more docile personality belie their Legbar heritage.
Thanks for the info. Getting some certain blue eggs is my main interest, with olive eggs a possible extra attraction. I have a couple maran pullets, cuckoo and splash, that I thought I could use. All the mentioned breeds would work for me, comes down to what eggs I can get I guess.
