I’m very sorry! Now is the time to get ready for a disappointing hatch (25%), you should still get chicks but far fewer than you hope. Your embryonic death rates will be higher and deformed chicks and failure to hatch rates will also be higher. You can’t do anything to fix the issue, the trauma has already been done to the genetic material, just incubate them normally and don’t worry about being upright or whatever, it might make you feel like you are doing something but that is about all it does. The air cell is just a symptom, not the main problem, my last two batches of shipped eggs got scrambled, interestingly the eggs with normal air cells had the same hatch/deformity/death rates as eggs with damaged air cells, it has nothing to do with air cell integrity and everything to do with stress/trauma to the natal genetic tissue, basically making birth defects way more probable and thus increasing embryonic death/failure to hatch. The shipper packaged them well but the post office played football and scrambled your eggs. Sadly just a risk of shipping and nothing you or the shipper can do. I still got a decent bird or two out of both hatches but i should have had a dozen!
