Hi, I am fairly new to this site so I hope no one minds me joining this thread so late. I have a small flock Black Coppers with a few Blue/Blue Copper pullets not laying yet. I have the chance to buy some Blue Birchen/Blue mix chicks. Are the Blue/Blue Birchen mix ok or will this mix just dilute the Birchen color too much? They will be seperate from my Black Coppers.
