This is a video of our first chicks hatching out in an incubator. Our hens were not setting well, so we borrowed a local schools incubator to try hatching them ourselves.
We found that, while not difficult in theory, hatching eggs yourself is quite a challenge. Our incubators were not in very good shape, and you have to keep the temperature and humidity just right, plus turn your eggs. We had 2 explode when they went bad, but 5 chicks out of the 8 hatched.
