A while ago me and my Dad bought a used TopHatch incubator from our local Value-Village. The incubator was missing some peices including including the fan, so we tried using it as a still air incubator but none of the eggs hatched. Recently my dad decided to give it another go, replacing the broken fan with the fan from an old computer we had laying around the house and now, 23 days later we have 9 out of the 25 eggs have hatched, (one other pipped, but was upside down, when we realized it was too late ) The morning of the 22nd day I candled the eggs and most seemed to be infirtile, but a few seemed to be fully developed and ready to pip, so I left them to go a bit longer but still nothing. A few nights during the incubation the temperature dropped from 99.5 to 98. Would this slow the hatching? How do I tell if there is any life? and if so, what can I do to encourage the little guys to come out? We did have a bit of trouble with the last 2 chicks, the humidity in the incubator went down and the membrane dried so we had to help them out a bit. Could this be why the other haven't pipped? The thing that I don't quite understand is, out of the 25 eggs we put in the bator, 10 were banty eggs, the other 15 were standard. All of the 10 eggs that pipped were Standard eggs, is this just a coincedence? This is my first time ever hatching eggs from an incubator so any help would be greatly appreciated.
