Hello, my husband and I have a small flock of 5 laying pullets, soon to be hens. They have a small run off their coop (about 8x10) but we let them out to free range for at least 4 hours per day while we are home. Unfortunately our yard is very small (1/4 acre) and neighbors are close. They are now going well into neighbors yards and into the road so we decided we can't let them free range here anymore. We were thinking about making a pen to go around the coop and run because extending the run with all that hardware cloth and making it predator proof would be too costly. So essentially instead of letting them out into the yard when I get home, I would let them out into the pen. Does anyone have any suggestions about this or the construction of the pen (height, materials, size, etc.). Also any ideas on how to keep them happy would be great. They love to free range and we really don't want them to be miserable. This starter home is just not the place for free ranging, as we've come to realize. Thanks!
