We are expecting our first fuzzybutts next week, and we are so excited! My husband has designed and bought materials to build the coop/run. He is wanting to lay "chicken wire" on the floor of the run instead of digging a trench around the run to keep critters out. Will this be ok? Will they just peck around the wire, or should it be underground? Not sure if this would make a difference, but they have more than the suggested 10sq ft. per chicken run (and 4sq ft in coop), and we plan on free ranging for a few ours during the day. Thanks in advance for your advice!
