I'm new to this and did a search and wasn't able to find it, and I'm sure it's been asked before just thought I'd start it as a thread to where it'd be easy to find for others that maybe come along and want to know as well. I understand that you have male lines and female lines due to the two being judged differently. But what are the differences between male line birds and female line birds. And what happens when you breed a male line to a female line? Do you get a bird that is not good for anything?
