Mama was killing chicks as they hatched 3 of 11, so we took the remaining eggs out and put them in the bathtub under a heat lamp with a thermometer. One of the eggs we think the mama had punched a hole in so we helped it out (before reading a great thread here on how to do it properly). Another hatched, seemingly normally and was active and alert. Having this one around the other has seemed to cause the first to perk up. It is finally moving after laying for most of the day. There are 2 others pipped and one with a bit bigger hole, I think that is called zipped. The zipped one has been at about the same situation for probably close to 12 hours. It's maybe a half inch by quarter inch hole. An acquaintance on FB told us she had to do this once with just a heat lamp and was successful. I thought humidity was a development issue and we'd be OK at this point, but now I'm worried. I don't have an incubator and probably couldn't get one here until tomorrow afternoon. Keeping the temperature around 100 degrees consistently is a bit of an issue as well. It ranges from 90-110. The two hatched chicks are not moving away from it and are cuddling. Any advice?
