Membranes look good, It shouldn't be stuck. Has long has it been since it has pipped? I would leave it alone, keep the humidity up and let it do it's job. Do keep an eye on the membrane though because once you remove that much shell it does have a higher chance of becoming dry because there is more air flow over the membrane.
Do you have a mobile device you can use beside the incubator? If you do play this video close to the bator:Thank you. It piped about 24 hours ago. And hasn't changed positions since. It's still breathing with the occasionally chirp. I moistened the membrane with some warm water and humidity is at 70
it also has been layike this for 3 hours moving and tweeting, shall I leave it in the incubator or put it in the brooder ?he had broke a small hole in the egg for around 2 days and made no progress so I went ahead an helped him out, all the yolk has gone but his umbilical cord is still attached? What should I exapect to happen ?
