A Time Lord's gotta eat, so daveninja built a chicken coop that looks like a TARDIS:
My wife read up about chickens and found that its good to have 4 sq feet pen hen for the coop and 10 sq feet of run space per hen. We planned on picking up 3 or 4, so we decided to go with 16sq feet coop and 40 sq feet run. 16 sq feet coop worked out great because then i could plan a tardis with 4' by 4' internal measurements and it would be close enough to the 2010 NST tardis.
The chickens will have plenty of room.
