When I peeked into the incubator earlier, there were 6 hatched chicks and several more pipped eggs! Hooray! I'll take them out of the incubator and have some cute floofball pictures to share later today.
Chicks can easily go without eating or drinking for ~48 hours after hatching (that's why you can mail-order chicks), and I don't want to open the incubator and drop the humidity while other eggs are hatching. But I'm also very impatient...
