Hi Riley,
I start so many of my posts with "I am not an expert", which is true in this case as well. I will give you my thoughts until the real experts show up :)
I would start by getting familiar with the breeding process in general before worrying too much about keeping track of and breeding for traits. While I have heard that AI is a thing, even with
chickens, I would not recommend it. I would stick to having a rooster in with the hens, and either using broody hens (my preference) or an incubator of some kind. In theory, hatching and raising chicks is not that difficult. I have done both methods and in both cases I was fairly successful, but I learned a lot from actually doing it that I missed from
books and youtube. I would work on getting high hatch rates, and raising healthy young chicks to adulthood before worrying about keeping records. Just my 2 cents.
I would also suggest (if possible) splitting your flock in two, or even maybe 3 flocks. Have several smaller flocks that are segregated would help in case of disease or predator as well as the ability down the road to have multiple "strains" to mix and match as you go.
Good luck.
