I have a question about free-ranging my chickens. I've been letting them out of the coop each morning into their fenced pen, letting them learn where they live, etc. I shut them up each night once they all go in to bed. Over the weekend I tried opening the pen to let them start really free-ranging, and they quickly ran out into the great big world. I watched them for a few minutes, and they were puttering around happily, then they spotted the horses and wanted to go back home. Unfortunately, they couldn't seem to find the opening in the fence to get back in the pen, and just kept trying to run through the fence. Are they going to figure this out, or what? Is there anything I need to do to help them, like paint a target on the gate or something ?
