yep, it's hard to believe what people will pay for eggs. But, I get very high prices off my rare bantams all the time. Price is based of, rarity of breed and color, supply available, and just how bad you want them in auction form. I say you go boy!
I just created lavender cuckoo d'anvers myself, well just finished them, been working on them for 3 years. I guarantee you they'll go high too, no one has them.
Most I have ever paid personally was $300 a dozen for some extremely rare wild turkey eggs.
Guess what, shipping or receiving, the P.O. has never lost a box for me, UNTIL they shipped them, they arrived 3 weeks later, just my luck.... Oh an I've bought Java peafowl eggs for $50 EACH, thank God, they all hatched. So in that case $50 got me a $500 bird when matured. It's just a gamble, as long as people realise that, go for it!
