I've bought 6 on ebay before. I like extras sent but some people send only 6. I like the 6 egg sales though as I can get a few different breeds to hatch and put them all in the bator at once. My problem is not with a zero hatch. Those things happen. My problem is when I bought purebred eggs and ended up with mutts. The sales person had a 100% rating and showed photos of purebreds so I thought I was safe buying from there
