My chickens are currently in one end of the barn with an automatic door leading outside. Right now they run free around my yard. The problem is they are digging up everything from my flowers to my garden! I have a fenced in "pasture" that I want to contain them in. My question is what do I need to build to get them from the automatic door on the barn to the "pasture"? It's about 10-15 feet away. Just looking for ideas.
