Thanks so much for the info! I will definitely keep in touch! I plan on doing 50 quail eggs from set to hatch. Usually if I dry hatch the humidity is like 15% what % does your usually stay at? This will be my first time doing quail!!
I personally would leave it. It most likely is getting enough oxygen and I wouldn’t want to risk ruining the rest of the hatch by opening up the incubator and shrink rapping them.
Leave it! If you’re really concerned try and take the piece off without opening the lid! A pip doesn’t need to be very big at all to hatch. Sometimes they are so small you can’t even see them!
Use a bright flashlight(or phone light) and hold it up to the egg in a dark room. Depending on how far along they are you should be able to see veins by day 3 and a full egg by day 14 or so
