I just purchased my second set of Orpington eggs for hatching on eBay. I drove an hour & a half to pick them up and found that all the eggs are small - probably from young pullets. Should I be concerned about the hatch rate being low? Will it still take a full 21 days for incubation? The seller has a 100% positive rating - should I put a ding in his perfect record? I'm really disappointed in the eggs.
