I left them out, they investigated the long grass for all of 20 minutes grumbling loudly and proceeded to stand by the gate with their heads buried in the long grass with their tales sticking up for the remainder of the morning ! I had worried in case I would not be able to catch them again but they almost hopped into the box for me! Back in their run they marched up and down squawking loudly, my hens do not do foraging they like their food and water provided!
