Oh dear. If 6 or 7 chickens went for the egg laid in the open it looks like they have learned that bad habit really fast.
I really think the roll away nest boxes are going to be the only solution and hope they only lay in them because it's obviously not just one or two birds in the flock eating the eggs.
