Depends on the species of pheasant.
Anywhere from the low end of $45/dozen to $100/dozen or up for 6 depending on the rarity and availability....some of the pheasants only lay an egg every other day.
As with any shipped eggs it's a gamble. I ship eggs in foam, which I think is better than other methods. In general, pheasant eggs don't ship as well as other bird eggs. I've got quite a few shipped eggs set right now and the 1st candling wasn't that great, around 35 to 40% viable.
Right now, I'm hatching alot because I'm replacing alot of my breeders this year. And some of these birds will take 2 years before I know if I want to use them for breeders.
Sorry, long answer for a short question!
