Hi. I'm hatching call duck eggs and one of them had pipped internally so I waited a day and then nothing. so I poked a small hole in the outer shell and when i did i noticed that the inner membrane is completely pulled away from the inside of the shell and has the duckling trapped inside. what should i do? there is slight blood but no obvious veins and it has been exactly 27 days today and the duckling is peeping. should i help or wait or what???? please adivse. already lost one in a similar manner dont want to lose another. thanks in advance
