I will trust our mods that if this is not in the best place for this post they will send it off where it would be of more help. I had an interesting conversation with a lady who works in the central post office wharehouse here in Houston yesterday. She said that all priority mail whether marked fragile or not is handled by a machine which dumps all the boxes into a hopper then on an assembly line and then sorts by zip code and dumps into more hoppers. So a box of eggs may have a 50 pound box of something come falling from pretty great height right down on to it. I never knew that the process was so brutal. Evidently the only way to avoid this and get special handling is to mark the box "LIVE" this is how they handle baby chicks, catapillar cocoons, crickets and other live things in the mail. From now on we will be marking all of our hatching eggs as "LIVE HATCHING EGG EMBRYOS". I shared this with someone who just got a batch of eggs from me that had a lot of ruptured air cells (as have several batches of eggs he got elsewhere) and he said he got eggs in Jan. marked 'live embryos' that did not have any... So... maybe this piece of info will help someone to have a better hatch.
