This is my first time incubating, I bought 2 brower top hatch incubators brand new at the local farm store. One I filled with 16 goose eggs, the other with 32 duck eggs. So far everything seems to be working fine, until I read up on the top hatch, apparently the light is supposed to turn on and off, mine just stays on and the temp is at 99.5 is this because they are newer models or do I have a problem? Also both machines make different sounds when turning which makes me crazy because I'm already nervous enough w/out the added worry that the eggs aren't turning correctly. I keep watching the little white turning hand underneath the unit to make sure it's in a different position, that's how I'm figuring out that it's turning. I'm also confused about the water situation I fill the line that wraps around the interior of the tray with water 2 times a week, is that enough, too much?? There is so many differing perspectives on the internet and the brower website is AWFUL!! Any tips or advice would be greatly appreciated!!
