I have to say thank you to all you fabulous people for the helpful information and advice. I've been busy reading and digesting everything. The AI led to sexing, which led to sex-linked traits, which led to breeding and chromosomal divergence, which led to an uncomfortable realization: I'm afraid Shelbydog opened a terrible Pandora's Box. I lovelovelove my chickens as pets, but in college I got involved with genetics as an extra credit endeavor (lobsters and regenerative chromosomes) and thoroughly enjoyed it, but seriously, how in the world do you work with genetics as a hobby, right? RIGHT?! I mean, without having government entities in bodysuits fitted with rebreathers descending on your house and having your property described as a "compound" on national TV. Well, there's pea plants and puppies.... but no, separate they're overdone, and together the musical was already made.
The important points to remember here are 1) Thank you all for all your great help! 2) Blame Shelbydog.
