I have 5 great birds that I let range freely, all about 8 months old, and 1 of them is an Aericana who lays green eggs. She was one of the first to lay and one of my most productive. About a week ago, I noticed that she wasn't layng. Finally, I figured out she just wasn't laying in the coop anymore! I found 3 green eggs under a shed. I have since blocked off that shed, but still no green eggs in the coop. How do I convince her to start laying in the coop again with all the other girls?
