Wow - that is awesome! I was thinking of pricing around $4 dollars per dozen. I use Organic non-GMO Feed too. We do let them free range - when they want to come out of the coop.  before the snow dumped we would let them out of their run to free range in our back yard each day for a little while. They have a tendency to want to wander into the woods. so for now, they are on supervised free ranging. LOL 
I will look into the poultry netting for next spring so they can spend more time in and around the garden too. that's a great idea!
