Currently I have a self sustaining flock of about 50 chickens, of mixed varieties. It has worked well, as I have large meat-type birds, smaller egg layers and little bantams, which act like the incubators for the flock. I would like to be able to ship fertile eggs to people on Native American reservations, so they can start their own flocks. The problem is, many people on reservations do not have electric. Currently, most incubators (if they could afford to buy one, which I doubt) run on electricity. At some point in our past, people must have been able to incubate eggs without electric. How did they do it? I have had success devising my own electric incubator, using a small pan of water placed over a little cage (intended to feed wild birds suet), with a heat light over it all, in a metal roasting pan. I had about 60-70% hatching rate. Does anyone have any ideas how a non-electric incubator could be constructed? I have plenty of fertile eggs I am willing to send to them, so even if the hatch rates were 40 to 50 % it would be enough so they could get their own flocks started. The idea is that people on the reservations are desperately poor, so buying birds would be cost prohibitive. I am reluctant to ship chicks, as it seems eggs might survive the journey better, but maybe that is a better option. Still, when they arrive, they will need a heat-source and it will need to be non-electric. Any ideas or suggestions would be greatly appreciated.
