My neighbor moved and left his chickens to fend for themselves. I have never raised chickens. Sadly there were 12 now there are only 4. I have been feeding them an just built a nice coop with small run. They sleep on our front porch (poop there too) how do I get them to understand the coop is a safe place? One will go in for food and come right out. They are very skittish. TIA.
