well...i definitly have some egg eaters . I don't understand what brought it on, they get oyster shell, plenty of grass feed and water, they have plenty of space and ample nest boxes. SO....i prepared a batch of mustard eggs tonight (blew egg shells, filled with mustard using a syringe and capped holes using unscented candle wax). has anyone ever had this work? I am also going to build some roll away nest boxes this week.
