The one to answer this is @WVduckchick . Her eggs were the best packaged I had ever seen. Our Chicago mail hub is one of the worst for shipped eggs. Even though the outer box was smashed, the instructions to call for pick up ignored, 9 hrs spent in a bouncing deliver truck on a 17'F day, and then dropped upside down on our doorstep.... not a single egg was broken and some eggs still hatched.I hope your hatch goes well. My Serama usually hatch at 20-21 days. I was wondering if anyone might be able to tell me the best place to get egg shipping supplies. I have 85 eggs incubating now. I thought it might be time to sell some.lol
