Hello, I have shipped Chinese goose eggs and all of them have a damaged air cell. Two are particularly bad. We are on day 29. Yesterday 3 were wobbling. When do you assist? When do i decide to drill an air hole? I am always reading that opening the incubator can do more damage than good.Perfect time for that question. First baby gosling hatched with no problems 2nd baby was ready to hatch but couldn't get out it was internal piped but couldn't pip its shell so I gave it and the other 2 with the bad air cells a breather hole. the 2nd one I ended up having to peal back the shell of the air pocket and it hatched normal from there. As for my 2 detached air cells they are still working on absorbing there yolks each in its own incubator wrapped in wet towels both are sticky chicks. Nether of them could get in position in fact I had a hard time finding there little beaks to expose them,. So time will tell we are on day 3 of a peal back on there shells they got there heads out this morning they are both finally trying to absorb there yolks. Im going to work this morning with them in wet towels my hope when I get home they will be ready to come out. As for the runners only one made it to hatch here name is East she piped on the wrong end. The breeder was great she reshipped me 13 eggs all are in the incubator looking perfect with embryo development.
