Oh, I hate to hear that!! As Dr. Tom Whiting said, "eggs roll better downhill". Meaning -- if eggs are laid at higher altitudes, they have a better chance of hatching at lower levels. Here at 8600' above sea level, the eggs hatched are typically more porous than eggs hatched "down below'. That's why people up here have a hard time hatching shipped eggs, but my shipped eggs are usually better! A guy in PA had 11/15 hatch.
Unfortunately, I can't replace them since my rooster died. I have a young son of his, though, that I'll be using once he matures (he's only about six weeks old now).
