Well, the best think to do is to begin to attend APA/ABA events and become part of the community; it will give you the framework that you need to breed chickes well, and it will help to keep you out of your head. When we're too much in our head, we start drawing conclusions that often lack basis.
It's not really a grand debate about inbreeding and outbreeding. To some extent you will practice both, if you're doing things right. What you need to begin is 2 to 3 pairs or trios, and from there it's about managing your pairings. There are a lot of poultry people in MN. Subscribe to the Poultry Press to get current on all the upcoming events, and then find out who's who in the MN APA/ABA culture.
It is they who will help you maneuver your breeding decisions.
Best!
