Ideas for A Broody Coop/Tractor

[new2chickens2011]

Juuuust in case one of my hens decides to go broody in the spring, I want to let her hatch some eggs, but I need ideas for a small broody coop that is easy and relatively inexpensive to build.
Show me yours!!

I don't have pics but mine is an A-Frame on a 4x4 footprint, with an attached 6x4 run. It was my first coop/run and worked great to segregate my broody hen as she was still able to see the rest of the flock but they couldn't get in an add eggs to her nest. After the chicks hatched, mama and babies stayed in it until the chicks were about 2 weeks old and then I let her rejoin the flock.
