Well that's probably not a good header for this question but I was wondering If I have chickens from the same hatchery what are the chances that they are too related to breed to each other? I was wanting to hatch out some of my partridge rock eggs in the summer. They are the same age and from the same hatchery I doubt they are related but thought I would ask here what you all thought. I don't want to hatch them if it will produce babies that aren't healthy. Sorry if this is a dumb question but I have always thought of them as siblings and now I am wondering what the odds are that they might be.
