Well its one of two things. It either has something to do with your incubator which it sounded like you were incubating fine. Number two which I think it is, its your male. If males are young they might not know what to do yet. It takes time for them and remember just because you have eggs doesn't mean they are fertile.
Also I think its funny you get eggs in November because its warmer where you live. Where I live I have to wait until April to start seeing eggs.
