I have a three month old Amercuana. I'm debating on wether or not to keep him for breeding because I want different colored eggs. I will not be showing these birds. I've heard that some Americuanas don't lay blue eggs and/or don't have the blue gene. Is this true, and if so, how do I tell? Oh, and while I'm here, I'm going to ask if he's a good bird if I should ever consider showing them in the future. Thanks for any input!
