I had a staggered hatch. I was incubating my own eggs when a girl at work asked me to put some of her eggs in my incubator. I was new to this and didn't really think it through before I said okay. Well her eggs were about 7 days behind mine. Mine hatched last weekend and hers were in there with mine during the hatch. I know this was hard on them. About 5 out of the 10 made it through and were showing movement. Welll I ordered guinea eggs that went in right after mine hatched. So my humidity for my guinea eggs is at 40% and her eggs are ready to hatch. One has pipped and I am not sure if it would be better for me to just turn the turner off and leave the incubator shut or if I sould open it up and add a sponge to help up the humidity. I don't want to get it too high and hurt my guinea eggs but I want hers to have a chance too. Aaahhh! I need another incubator!
