@WVduckchick The eggs I'm stressing over now were 14 days old when set. I think they're the oldest I've tried so far. Usually with anything over 10 days old I get mixed results. Some never develop at all, some hatch on time with no problem, some are late, some need assistance at hatch but grow out just fine. They're def more likely to be trouble makers when compared to fresh eggs. I like a challenge.....sometimes.
yep, i definitely prefer fresh eggs, but i had room and wasn't going to use those eggs otherwise so didn't have anything to lose. But i agree, you never know what you'll get really.
