I got a Hovabator with automatic turner last year, and I've used it 3 times. I got excellent hatches last year, the best being 31 chicks out of 36 eggs. I just set it up for a test run, and had it running steady for 2 days at 100*. I then put 18 of my mutt eggs in, and didn't change anything else. By that night, it had shot up to 113 for what could have been up to 6 hours :-( That was 3 days ago, and I candled some of the lightest brown eggs, they were all clear. I just don't understand why this happened and what is up with my incubator!? Anyone else's Hovabator ever done something like that? I'm starting to think I could do a much better job with a homemade incubator!
