The Dominique is awesome. Our hens started laying over a week ago, the RIRs hatched at the same time (and fed the same feeds) are still not even started. Meanwhile we have three hens laying a beautiful egg a day, with more of our hens getting that magical egg laying look in their eye.
Our Dominiques are also great foragers - we are hardly going through chicken food at all since we moved them out to the big coop where they free-roam the property for bugs and greens. I've found myself dumping their feeder out a couple of times because I was worried the food had gone stale and that's why they weren't eating it!
