Forest Feeding Chickens

In our quest for a leaner and healthier yolk, we have decided that just feeding the chickens good food wasn't enough, they need to exercise to aid their digestion, and to pump all the nutrients in their blood around their bodies. When a chicken feeds from a feeder, they feed until their gullet is full and then they just hang out, digest some, and poop a lot.  But when they eat in the wild, they peck once and scratch twice, repeatedly, all day long. Eating this way causes the chicken to eat more slowly and the constant exercise provided by all that scratching means that the chicken is better able to better utilize the food they eat. 
We decided to stop feeding the chickens in bowls, or even simply scattering grains on the bare ground. What we are doing now is taking a bag of mixed grains and seeds into the forest to scatter among the fallen leaves, moss and grasses. The chickens seem to get almost all the grains. (what they don't find should sprout, the grains are even better when they sprout.)
We have been throwing the seeds out in the woods for the chickens. We feed them in a random rotation to keep them from over scratching any one area of our property.

The chickens are actually requiring less seed overall, because they are getting more moss and other forest goodies along with the grains we throw, there has been a rise in egg numbers, the shells are firmer, and the yolks are darker and more translucent, and therefore less fatty.

Egg Shooters

We also noticed that the chickens seem to be having an easier time laying, because they are all spending less time sitting in the nests, they just hop up lay, and move on. Perhaps all the work spent scratching in the woods is toning up their egg shoving muscles.
