I am getting ready to put eggs in our new Brinsea OVA-easy Incubator. We tried putting eggs in late last fall--no chicks. We did have a few mishaps. The Trays didn't come with the correct holders, and the ginormous Buckeye eggs broke free. Then my AM humidity tray checker wasn't checking, and it was going dry. But now we have propper egg holders so no worries about that now, and I'm just going to monitor the humidity tray myself. I've got it on. It is holding temp at 37.8C which is right on. We've got it in the basement, steady temp 70F, steady humidity 38%. My big question is about what humidity in the Brinsea itself. The instruction booklet says "fill humidity tray"--Not enough information!! We are at 990 ft above sea level. I used a old school Hovabator previously (no fan, no turner), but have no experience with this fancy fan and self turning stuff. Help!
