Unexpectedly chickens

On Friday our neighbour turned up with three chickens in urgent need of a new home. Since the last of ours had recently has away, we had an empty coop and could hardly refuse. They were pretty flighty and nervy the first couple of days, but they're getting used to us now and we let them out into the bigger run for the first time today. They loved it and are now moaning they want to be out all the time. Typical chickens.
