Hey, you won't believe how much fun this can be. Just got a hovabater incubater last month. Took eggs and decided to hatch them, only colored, as I have plenty of leghorns. My rooster is Americauna and have barred rock, australorp and 1 rhode island red for brown eggs, and 1 Americauna hen. Learned at ten days brown eggs have to be candled in the dark, couldn't even candle the green eggs. With 22 fertile eggs, I hatched 19. Now have 8 out of 12 duck eggs, given to me by the feed mill, just for fun, should be hatching in about another week. After that I plan on hatching about 30 for friends. My chickens produce about 15 eggs a day, so I'm hoping to keep this hatch at about the same time. My temp actually fluctuated 2 to 3 degrees off and on, and I can't measure humidity, just kept water in the base. Chicks didn't seem to mind, hatched on 21 days just like clockwork. OK, maybe a couple at 22 days, probably my fault. Good Luck with your chicks, this is easier that many people make it seem.
