Today is the day we make our cut to the final 6 hens we will keep (that's the max our city allows). When my son and I started this project we used the guidelines on the Raising Chickens 101 page to construct our coop. It says to allow 2-3 sq. ft. of space per bird in the hen house and 4-5 sq. ft. in the run. Now reading in this section of the forum I keep seeing 4 sq. ft. per bird in the hen house and 10 sq. ft. in the run. The coop, except for the wire, is finished. Given our space and the city's restrictions on where we could build, we ended up with 3 sq. ft. per bird in the hen house and 6 sq. ft. per bird in the run. Will this be adequate for healthy, happy checkens, or should we reduce the number of birds (we'd hate to do that, we've become very attached to our final team!)? Why is there such a discrepancy?
