So I'm a complete noob with chickens. I've keep them at their coop/pen for a few weeks, I believe it's around two plus so far. My goal was to have them to free range during the summer days. Witch I've been slowly keeping them out longer and longer each day. All has been going extremely well if anything alerts or frightens them they head straight for the coop. So today I arrived home from work extremely early to find them MIA (so I thought). So apparently my wife took off for lunch with a friend and left them outside. Long story short they are completely fine hanging out in the woods at the neighbors. They where happy as a chicken could ever be. Some how I was the one worried about them though. Plus I think they were getting spoiled at the neighbors (they use to have chickens before). So my question is how far is to far before they get lost if possible? Apparently they have been having a grand old time today as they could care less about their fresh food I gave them after walking them back to the coop.
