Hey guys I need some advice. We are having to relocate and at our new location we have neighboors. We currently let our hens run lose but would like to add a chicken run at our new location to keep them away from the neighboors place. How large of a run would I need for about 25 hens? How tall should the fence be? We have two coops one 10x10 and an 8x8. Any other information would be helpfull, thank you.
