Alright so I decided to wait till today to remove the tape just in case so I can reduce the time of the membrane being exposed. So I removed it pretty quickly while misting water in the incubator to hopefully compensate the loss of humidity and after, both eggs started shaking a lot. I'm still really concerned about shrink wrapping. Would they still be shaking if they were shrink wrapped? Also I haven't heard any more peeping just the one last night and then nothing. Thank you again so much for your advice in this. I really want to see these duck hatch safely
