Brainstorm ... would this work?

[SunnyAlberta]

For two to four hens, would this work as a run or tractor if it had a roof and wire over the windows? Ideas? Its 54 x 54 x 63, I think. Is floor space more important than height?

They need enough height to roost off the ground a bit but yes floor space is more important.
