I"ve never had chickens before and I'm expecting my chicks to arrive tomorrow! My husband has been building a nice chicken coop for them. We've been shopping for wire for the run and decided we like the welded-wire fencing look better than traditional chicken wire. But it comes in all sorts of sizes...2"x4", 2"x3", 2"x2", 1"x1", etc. We have found that the biger the holes, the less expensive it is. Any advice on how big you would go? We don't plan on raising our own chicks from eggs, so it will just be adult chickens in there. Do you think 2"x4" would be too big? Thanks!
