I have had Bourbon Reds for a couple of years now, and I have a neighbor who just started, also. My birds are free-range and they only lay and hatch in the fall. Because I live in far northern Wisconsin, this can be OK or not, but it is odd to me. Actually, we just had a hen show up with new poults today. The hens so far have been very good mothers. They keep the poults far away from the Toms, who will kill them, and will actually fly up at and attack hawks and eagles trying to snatch them. I actually am not sure that incubating eggs is a good way to rebuild a hearty breeding flock. The point of these heritage breeds is that they do it themselves and there is natural selection going on. I will continue to order birds from different sources in an attempt to rebuild genetic diversity and let the birds work it out.
My hens sneak off and lay somewhere obscure. If you discover a nest, it is a mistake to cut anything back or make any sort of path to it. The hen will die and the eggs will be eaten. On the other hand, left to themselves, they seem to do a good job. We even tried building a defensive enclosure around one nest and the hen stopped sitting. Gotta trust them to do it, and we have to let the best of the breed rebuild its natural characteristics.
Just a note: my neighbor and I have both noted the COMPLETE disappearance of rats with our free-range Toms on patrol. They don't like them one tiny bit.
