When my quail eggs were shipped to me from PA, they arrived in a box with a layer of shredded paper on the bottom, then a row of plastic quail egg cartons which were all taped together, then more shredded paper, then another row of cartons then another layer of paper to seal the deal. Each carton of eggs had what looked like toilet paper rolled up and placed between the rows in the carton.
I had 120 eggs shipped to me and only 4 were cracked upon arrival!
Now i am wondering something.............instead of shredded paper, i wonder if popcorn would work, popped of course! One of my kids just had the egg drop competition at his school where they dropped the eggs and their protective contraptions off a two story building, and his survived!! We microwaved a bag of popcorn and put the egg in a sandwhich baggie (incase of failure!), dumped half the bag out, put the egg in the middle and put the popcorn back in.
Now talk about environmentally safe! Dump the popcorn in the yard for the birds to eat!!LOL
