HELP! I have a chicken egg I noticed pipped this morning but he hasn't broken the white membrane under the shell. I noticed it around 730 so it's been at least 3 hours ( probably a bit longer). I have a duck egg that's also hatching in the same incubator . I haven't seen the chicken egg move, heard it cheep, or seen any progress. Could he have suffocated since the white membrane under the shell is still intact? I'm scared to open the incubator since I have another egg hatching but I'm wondering if I need to break that membrane.
