How big for up to 6 chooks?

[eksterhuis]

I am looking at designing houses for my different breed pens... Just wondering how many square feet of coop I would need for up to 6 chooks. They have a free range pen and no predators so the coop only needs to be for laying and night time roosting!

Thanks

Approximately 24 sq ft. About 4 sq ft per bird. You can get by with a little less.
