I built my incubator and also a hatchery but its my plan to let my chicks hatch in the incubator and the move them to the hatchery for further growth. I have also build a chick rearing area for their next stage :-)
I am not sure how important all the tech is as when my birds are looking after their own eggs they don't have aids!! How does a chicken change the humidity? I have 94 eggs in my incubator at the moment, these are all different as in duck, chicken and guinea fowl. All due at different times...
