Hi all ok i have been doing a lot of reading on this site and i was able to get the average amount of square feet one chicken needs 4 ft. I just asked my mom how many square feet our coop is and she just gave me a blank stare. I think it must be the same look i give her she is right! she did look at me like i had lobsters crawling out of my ears!!!! her fovorite thing to say to me right now! I want standard size hens but i do not want them stuffed into an area that would be to small for them. So here is my coop size i just went out and measured it. the house area is 5'9" x 4'3" and the attached run is 10'3" x 5'9". Sorry i just am not sure how to figure this out and school so far has not taught this yet I am just thrilled our new house we just moved into has a pre-built chicken coop!! yippppeee oh and thank you to anyone who helps me out on this!
