So I've been trying to educate myself on chicken genetics. Some of what I've read makes sense, but being different from plants and mammals, I get lost easily. I found a nice little series of videos that I found pretty helpful though. I thought I'd post it in case someone else might want to waych them. It's nothing advanced, but helped my understand some subject better.
There's like 7-8 more videos in the play-list on her youtube page.
