My only experience was a few months ago, eggs I purchased of the BYC classifieds. The box arrived with the corner bashed in. CR Farms had packaged the eggs so carefully that they all appeared beautifully intact, however when candled they were completely full of hairline cracks. No fault of theirs but the postal service as is the case a lot from what I hear. It's risky, I ended up with 1 $35.00 Splash Marans (roo of course). I would recommend them though if you were going to do it anyhow, they did pack them perfectly, and had a nice variety , and sent 4 extras.
