So I have a hova bator still air incubator with the turner. I got it last December and tried two incubations back to back. Nothing hatched out of about 20 eggs between both settings. The third time I set well over a dozen and only 3 hatched. I was concerned about the first because they weren't shipped eggs. But I didnt stress too much because it was the first time. The second was shipped eggs so I wrote off as a failure with shipping. The third time I was concerned because they were all home grown eggs. Yesterday was my hatch date for my fourth setting and I've only had two hatched. I've had at least 3 others attempt but they appear to be dead now. I had about a dozen out of 30 eggs not develop. And I know they were fertile. Only two live hatchlings out of the remaining eggs so far. I'm a bit Frustrated and unhappy with my bator. Any advice?
