I have been having horrible hatch rates lately, like zero. I ordered eggs from RAREROO, he did a great job getting them here, most of them delevoped beautifully. I ran the Hovabator at 99.5 to 100 degrees as it is forced air with humidity between 30 and 50. When it dropped to 30, I would add water, candled they looked beautiful. Then because there was also duck eggs in there I moved them over to a still air LG at 101 to 102.5 degrees with humidity at 70 and they didn't hatch. They were all formed, completely formed and didn't hatch. The duck egg was suppose to hatch today, it didn't, I didn't wait, I opened it and it was dead, fully formed. Why are they forming but not hatching. When I candled three days ago, it was dancing in the shell. I have more duck eggs in there the Hovabator and they will hatch (I hope) in three weeks and they will hatch in the Hovabator because after this I am done hatching. This is devasting. I have hatched before but also in the Hovabator, could it be the LG, which I borrowed or what????????
