Very similar to this one
We thought it could stand on the grass with a 'pathway' of paving slabs around the edge to deter foxes from burrowing under. It would be too heavy to move around the garden but the chickens could, in theory at least, come out (or perhaps move into a portable run) during the day.
Would it work? Obviously we'd need to build perches into the indoor bit. What other modifications might we need? We had 3 chickens in mind, but may want to add more later if space allows.
TIA
