I am SO EXCITED!! I am hatching eggs in my 6th-grade classroom. As you can see in the photos, I had 3 hatch overnight, 1 hatch just now, and several others have pipped. The 3 that hatched over night are getting pretty dry and fluffy already. Should I remove them from the incubator yet? I do not want to harm the chicks that have pipped by opening the incubator but I also read to remove the chicks when fluffy. I leave school around 3:50 and won't be back until tomorrow morning so I also want to make sure I do the right thing for the chicks. Any help would be appreciated!
