Knowledge is power, but you could get your point across being less confrontational. This is just a hobby from those here on BYC that hug their chickens to those that show. We are fortunate to have some experienced breeders that are here to offer advice to those that have questions and continue to move the breed forward. My take on white Dominiques, they do not have a place in my yards and if they popped up they would be culled out of the hatcher. Never seen them, never will raise them.. Simple majority rules. I am more concerned about improving what I have in front of me.
So you would kill a poor little chick that can't defend it's self just because it a different color? Just because you have it doesn't mean you have to breed it. What about the chicks parents? Are you going to cull them because they produced a different color offspring ? doing what comes naturally. It's called evolvision . That is kind of cruel, you might not want that breed in your backyard but if evolvision didn't happen you wouldn't have most of the breeds today. But in the end it your thoughts and your own choice
