so I've been selling and buying hatching eggs for a while now. I think we all realize that its a gamble with shipped eggs. I wanted to ask other sellers what they do with customers that end up with a 0 hatch rate. Should I replace the eggs? Should I ask them about their incubating technique? Should I just say tough luck, not my fault? For buyers, what are your expectations in this situation? I want to do the right thing, but I know that I'm getting good hatch rates here at home so I'm guessing there was a problem during shipping or during incubation.
