I am seeking tips for success on this. We have Welsh Harlequins and are considering Anconas, but we have also have a Khaki drake and a pekin and a rouen hen. We will be incubating the eggs, but am wondering how to separate them to maintain the breeds. They free range during the day (well, right now, they just hide under the pine trees because it is too cold...not sure I would actually call that free-ranging, LOL) and are cooped together at night. I know that I will need to separate them, but am wondering for how long they need to be separated and how best to make that happen. Our kids are looking at 4H and we also want to maintain breed quality on the rarer breeds because we think it's important.
