I've read this board and other resources for YEARS before finally getting our chickens this spring. Since our coop is roughly 4'X5' I limited ourselves to five full sized hens at first. But, I noticed that even though the coop is smallish that they only use a fraction of it- at night they all huddle into one tiny corner and they spend virtually zero time in there during the day. They're outside from morning to dark. I had the opportunity to "adopt" a few more hens and now we have eight in that space. I haven't noticed any issues with odor, birds seeming unhappy/crowded, etc. If it makes any difference they free-range in our yard (1 acre) most of the day. They also have an enclosed run (140 sq ft total) for when we can't be home to check on them throughout the day or if we think we won't be able to make it home by dark to secure them. Am I really going to end up regretting this and need to re-home a few hens this winter or are there some birds that really just don't seem to need as much space as others?
