I don't feel so bad having to help these guys then. They started out under the guinea hen and something was eating them so I moved them to the incubator, then we moved them under a broody 4 days ago and moved them back to the incubator when they started pipping. Talk about human interference
But I sort of saw these as an experiment because I didn't want Guineas anyway.
I do the same thing as you with the incubator-don't even pay any attention to the humidity until day 18 then jack it up til it's sweating. I have yet to let any hatch in the 24-egg Brinsea. I've so far transferred them to the 10-egg to hatch because I can't seem to refrain from filling the 24-egg with more eggs.
