Our five girls have been using their nests like clockwork. Now all of a sudden (for the last week) we are finding from 2-3 eggs laying in the poop board! How do we get them to stop? I put golf balls in the nests last night to re-train them but this morning there were 2 eggs in the poop board again! We are baffled! Any suggestions on getting them to stop? By the way two hens are 1-1/2 years old and the other three girls are fairly new layers. It's the small eggs we are finding in the poop board as I think about it.
