@Shadrach I have read all of your stories. Honestly there’s nothing new there. There’s thousands of people that raise chickens similar to you but they don’t sit and overanalyze everything. They don’t simply because it’s not needed. The chickens do just fine free ranging and coming back to their coops to lay eggs and sleep for the night.
You mention the origins of chickens in your articles. Why don’t you try raising gamefowl. They are far stronger and more disease resistant than the birds you currently have.
People have raised gamefowl totally free range on walks for a very long time. As I said I do believe your trying to reinvent the wheel here.
Where you are located your system may work perfectly but someone who receives multiple feet of snow in winter it could be a disaster.
Everyone’s location and space is different. There is never going to be one system that works best for everyone.
I have many free range birds that were hatched on the ground, raised there and sleep in the trees.
I’ve never taken a chicken to the vet and don’t plan to.
