My wife an I just moved onto 5 acres there is a metal building Barn with three stalls in it. I am thiniking that I can convert one stall into a chicken coop with laying boxes for the chickens and let them runn free on the whole of the 5 acres during the day. IS this logical or should i also build a fenced in run for them. I have 60 eggs incubating currently in my classroom that will hatch around the 25th of this month. and am planning anothe 60 to follow. My sons have decided that selling yard eggs and gardening will be their job while in school i have three boys ages 9,12,and 13. I grew up on a produce farm so can help with that part but am new to chickens. ALso what do I need to do in the stall it is 12'X12' and has a natural floor used to have horses in it evidence is still there.
