We have to take out some smaller sapling trees around the new walk in run this weekend. Should I just let the chickens be how they normally are in the larger fenced yard or should I put them all in dogs crates and move them while we chain saw? I don't want to freak them out. When we were drilling all the run together they didn't care, but the chainsaw might be a tad louder. We'll be finished in about 30-45 minutes at most.
