I was going to try this as a last resort(i do think they kinda know the diffrence between fake and real eggs) but.....the new to start layers( and ones not laying yet dink around so much in the nests they scratch break and peck dents so i am trying to collect as much as possible so they don't figure out how good their own eggs taste!! the girls that have been at it for two weeks now are no muss no fuss now in and out, i hope to keep it that way!!.I take one of the eggs that was layed on the floor of the coop and mark it with a sharpie, and then put it in the nest boxes. Usually does the trick![]()
