I'm going to assume you weren't trying to sound as rude as I read this as, I know text can convey emotion poorly for people.Ok so you listed 2 separate hatcheries that have a sex linked Amerucana and a sex linked olive eggers.
My hatchery guaranteed pullets.com would offer black sex linked hybrids that lay every egg color.
People could buy them in variety packs and get pullets that lay 1of every egg color.
From 1 order placed by 1 hatchery.
Plus newbies would fall for my rooster buy back guarantee.
There many that people want pullets and they want all the egg colors.
There not going to care about other stuff.
This will give me a leg up on competition.
I was only offering places that have sexlinks that lay other than brown since you asked us to tell you what hatcheries offered those colors
