Try fermenting your feed. Go over to Bee's thread on the Feeding and Watering forum to get the details. In short, fermented feed is easy to do and releases all sorts of important nutrients such as natural pro-biotics. It increases the taste factor and chickens adore it. It also eliminates all waste since it's in a moist form and you feed it twice a day instead of leaving it out all day for the chickens to play with.
In the four years I've been feeding FF, the results have been nothing short of stunning.
THANK you thank you thank you--I found the thread! I am starting some fermenting right now!......The former free rangers need some major incentive to eat feed and this sounds like the answer.
