VegasChick - Oops - I fixed the link to the other aquarium bator (she hatched ducks in it)

I'm pretty optimistic about it working, but just remember - this is the first time I've used it (or any incubator) so I can't guarantee how well it will do yet. So far, it's held constant temps for 36 hours. I've added a tiny bit of water a couple times to keep the humidity up to 30-35%. I'm using the dry hatch method (see below) so a 25% humidity is still okay, but I want to keep it a teeny bit higher.
gckiddhouse - I wanted to copy another member's idea for the turner, but couldn't figure out how to make it work with a glass enclosure. Since I already had the PVC pipe (found in DH's shed), I happened upon gluing pieces to the bottom. Here's a link to the one I wanted to use - might work perfect for you:

Yes, it sounds as if the humidity is too high. What does your humidity monitor say? I don't have any water in my incubator right now - other than adding 1/8 cup twice so far to keep it above 30%. If you are wanting to keep it at 50%, you will need to keep water in the dish though. I will be using the dish & sponge mostly for the last few days when I boost the humidity up to 65%.

Mahonri was successful at it too - I hope it's okay that I quote you, Dar.
"I'm a big believer in a dry hatch. 25% to 35% humidity for days 1-18 and then 65% to start day 19.
I always candle at day 10 and day 18. I started with 65 eggs and at lockdown had 48... 41 of which hatched!"
