x2The only way to make them stop is for everybody to stop buying their chicks or for everybody who does buy them to complain. I watched the name change from Auracana to Auracana/Americauna because tons of customers contacted the Hatcheries and said "these are NOT Auracanas, they have TAILS!" Soooo... the hatcheries sort of stole the name Ameraucana, some changed it to Americauna, and continued selling the chicks.
Some hatcheries have changed the name, or at least added "Easter Egger" to their name. This was done because of customer complaints. If you want to make a difference, everybody contact them - multiple times!
I've too have noticed that in the few years I've been raising chickens, some of the hatcheries have come around and changed the name to Easter Eggers. I feel pretty lucky that the very first eggs I ever hatched were a mixed batch from My Pet Chicken, and were properly labeled Easter Egger, so I never had to learn the lesson the hard way. I wish all the hatcheries did this. I loved my EEs right from the start, and never had to feel like I had been ripped off or lied to. Later after coming to BYC and meeting so many wonderful chicken folk, I started getting my eggs from reputable breeders.
