Hmmmmm personally I would be a little bit concerned if all the eggs were the same. I don't have too many suggestions except that I would let nature take its course. I say this with full knowledge that when we artificially incubate eggs we are interfering with nature but in this case I am not sure what can be done. If it were me I might try to lay the eggs on their side in the hope that the cells may alter. What I do think is that like a difficult pregnancy, you are going to have to monitor the development closely and candle more regularly. When I candle I do it on day 7 day 14 day 18. Provided there are no external pips early on day 20 I weigh a sample of eggs to establish average weight loss which determines whether I add water to the incubator or not. I suggest that you keep monitoring them and see how it goes. You are surrounded here by people who are prepared to guide you so don't panic. It always pays to check air cell placement on shipped eggs before incubation commences. I have some theories on the relative lack of success on shipped eggs.
