My I have 5 hens and a rooster. Went out to check on them like we do every evening and found 1 egg in nest. No one sitting on it. This morning I go out to feed and water them and check for anymore eggs. I have 2 fake ones in there and couldn't find them so I dug around in the bedding and found another one plus my two fake ones buried in the bedding. Is this normal and why aren't they sitting on them. They are first time layers. Please help. Not sure what to do.
