I have hatched many critters and this is my first time seeing this. When I candled one of my Pilgrim goose eggs, it's air cell is so large that it takes up most of the egg. It's only on day 10 of incubation and the other goose eggs look just fine. I see the embryo is growing and moving, but it's getting stuck by these pockets, so turning this egg is almost useless. The air cell isn't moving or anything. This is only my second time receiving shipped eggs (usually have my own eggs or get them locally) , so could this be due to shipping? I'm pretty sure this gosling isn't going to make it. I was wondering if anybody knew what this was? Any experience with this? Here's a diagram to explain this egg... blue being the air cell obviously
