I'll have to do some research next spring. I'm only allowed to have 5-7 total with our lot size. I'd probably only do 2 more because it would overcrowd with more. I love Buff Orpingtons so they've been my plan until seeing the blues!We do have them here. I have a Blue Australorp rooster, and some Blue Australorp hens. I also have the Splash colored ones, and the Black ones. Mine are the breeder's type though, not the hatchery ones.
