Yes. This is something I read today. I have been doing a lot of research every moment that I could today. While I have been raising chickens for several decades I have not dealt much with shipped eggs or incubators; only on a very limited basis so I have a lot to learn. I'm going to candle the bantam eggs again to verify just what damage there was. The air cells were ruptured as the air floated to the highest part of the egg as it was turned. I'll look to see if the yolk membrane was also broken. In that case I do not think anything would have helped. I had put these eggs under a silkie hen who is a reliable brooder so I am sure any damage was done in shipping.
Ya, not much you can do if the yolk is scrambled. Sounds like the packing could have been a bit better or the PO played football with them. I have steered away from shipped eggs for this very reason. I have awesome hatches with local eggs and my own eggs, and I'm leery about spending money on something that may or may not yield anything. We have plans to get shipped eggs next spring, so we've been sharing a lot of info on what has and haven't worked for those who have done shipped eggs. And how to pack for the best protection. I have heard that people that ask that the box does not contain any labels or stickers that say there are eggs inside fair better than those with boxes labled as fertile eggs. Makes you wonder....After candling the six eggs four had ruptured yolk membranes; the insides were thoroughly mixed.
