We have about 40 or so free range chickens, they roost wherever suits them in the barn at night. Its been getting harder and harder to locate the nests to harvest eggs, they have them hidden in all kinds of nooks and crannies, and theres plenty of nooks and crannies in and around the barn. They pretty much ignore some nesting boxes I built. My wife is of the opinion that a lot of the chickens are laying off in the woods, real thick brush in there, you'd never find them. Regardless, buying chicken feed and also buying eggs is kind of chaffing me, to say the least. We figure the best bet is to put some of the chickens up in a coop where we can lock them up at night. I want to fence the coup in, wife says she would prefer to allow them to free range. Which option, fenced in or not, would you prefer, being as you were looking to harvest eggs? Also, there is a small shed that is abandoned on the property that I would like to use as a coop. It would take a bit of wrangling to drag it out from wheres its located to a more suitable location, but nothing ginormus. The shed is 4x6. The peak is 7 ft. About how many chickens/nesting boxes could I put in there?
