Ok here I go again.
I have ordered eggs and figure if I can get 25% to hatch that would be good. I also like to order enough to allow for damage. My concern is the gene pool and keeping it deep. I don't think I'd order eggs just for chicks. (no pun intended). I've got some hatchery birds that are very pretty.
I worked for the po for 18 years as a letter carrier. I've delivered bees and pigeons and chicks. My advice is pick them up at the po. Check to see when the truck arrives and go get them. I picked up my chicks at 6:30 am. I had them call me when they arrived. I will call them on the day I expect my eggs after letting them know I'm expecting them.
If you ship eggs why not post on craigslist for bubble wrap, save any styrofoam packaging from computers etc. etc. the heavy sheet stuff, to line the sides and bottoms of shipping boxes. Talk with the people at the local
Walmart, Dollar store etc. etc. Use a box that's bigger than what you need. Leave a good amount of space all the way around. Put the box inside another box.
You might be surprised to know this but "Flat rate priority" is not always a good buy. It's only good if you have something heavy to a certain point. Eggs don't weigh that much so you might avoid trouble by using a bigger box.
Personally I would rather pay extra for a higher shipping cost if it would give me an edge on getting viable eggs.
As far as insurance goes check to see if what you ship is coverable. The clerk won't tell you if it is or isn't, if it means a bigger sale. Sentimental items aren't. Saddles are and it's up to you to follow up your claim. Also the po won't pay more than an item is worth even if you insure it for thousands more. Then there are those who insist against good advice. Take the time to write to the Post Master in your "State". E-mails are easily dismissed. A letter in hand is much better.
And then I'm willing to pay more for the shipping than for the eggs if it increases my chance of getting viable eggs. I would not order common breeds either. Unless I absolutely had to.
