I am hoping to hatch some chicks in a lg incubator that I was given. My concern is that my eggs won't be very fertile. I have 1 banty roo and 7 large breed hens. I wanted to start by trying to hatch my own eggs rather then spending money on eggs for my first few attempts. Now I am concerned that my eggs my not be fertile beacuse of the size difference from roo to hens. Any thoughts? Also I want to do a few weekend camping trips over the summer and want to have the chicks outside before I leave - how far in advance do I need to hatch before I can transition them to the flock? I will have someone at my house the whole time I am gone and a friend who will come and gather eggs and let the chickens out in the am and shut them up at night.
