We have a lovely and pretty clean hen house that has an elevated platform with a water dispenser and a feeder. (The automatic waterer and the main feeder are in the run.)It is also at the level of three windows that our girls use to take in the world (of our back yard) and to sun themselves. The platform also has a nice bed of pine chips and enough space so that the five hens spend allot of time searching through the bedding for something to eat as they enjoy their good fortune. They nibble up pieces of the pine but we thought it would give them pleasure if they actually found something nourishing to eat. Should we scatter some feed into the bedding and if so, what kind? Should it be different from their regular feed, to add interest?
