If you want quality Speckled Sussex, do not go to the hatcheries. Just not there. If you like their stunning beauty and great temperament, buy from a breeder. Esp. in the Speckled variety, It is the toughest color to breed in Sussex, being a tricolor. Takes decades to get the gene pool stable enough to get a nice pattern to replicate regularly from generation to generation. The three top strains of the Speckled large fowl here in the USA are ( In no particular order) Walt Reichert, Gary Overton ( Mr. Sussex) and Tony Albrittion. You want to either buy from them or someone who very recently bought from them and/or has not crossed the strain into another strain. In Speckled, esp, do not cross strains to found your flock! That's very important. It will mess up the stability of the gene pool and take years to straighten out the color, unless you are a Master Breeder.
I have contact info for all of the, just a sec, while I look it up.
So the hatchery birds tend to not have the same temperaments as those from breeders?
