All of a sudden some of my layers are laying their eggs in my hay room. I found 2 clutches of 12-15 eggs each. One even made a tunnel in between two hay bales. They have nice, clean nests but I noticed that there were less and less eggs in the boxes. They can access the stall with the hay since their converted stall/coop is right next to the one with hay. I have plastic netting on 2/3 of the top of the stall since the stall on the other side also has hay in it. I guess the only way to stop them is to totally net in the remaining portion?
