I just threw away 18 Sebright eggs that I carefully monitored, making sure they were turned at least five times a day, and always an odd number of turns. The humidity was right on till the very end, on day 18 I bumped it up to the recommended level, and I faithfully refilled the water reservoir whenever the humidity was even a few degrees too low. Nothing hatched. I ordered a barnyard mix off Ebay, set them after letting them settle over night. I had the incubator warmed up and the humidity was at the right level. Then I forgot about the after the first week and didn't turn them or look at the humidity, till I noticed it was Day 18 and time to lock down. I refilled the water reservoir, but I didn't think much would hatch. On day 20, 3 little Silkies hatched. The next day I had 3 Americauna, and 2 Leghorns. Now I've got another Americauna that just popped out on his own with no coaxing from me. There's one more egg left, a light tan colored one that looks like It could be an Australorp. Its pipping and peeping. Wow, neglect is really the answer! All chicks are well formed and vigorous.
