I have two family groups that I've line bred probably to the point where all they do is produce females - perhaps a bit to inbred. It's kind of maddening because I can't progress my line at this point, I literally have couples who have just daughters their entire breeding lives.

I am hoping for suggestions or theories on how to pull some male nests from my line - short of throwing some new blood in the mix. Since this is all speculation, I wonder if adding new genes into this family will help pop make nests or is it all mathematics and something to do with the servers. I line breed religiously but I'm starting to wonder if I've just overdone it to the point of just producing one sex. Help! lol
