I have 8 laying hens, I have a variety of breeds so I have many colored eggs. I have green eggs, blue eggs, speckled eggs, brown eggs and white eggs. They have been laying well for two years I get an average of 7 eggs everyday. This year they have begun scratching the bedding from their nest boxes and laying eggs on the floor of the hen house. I'm wondering if anyone knows why they are doing that and what I can do about it.
