Hi im new to the chicken experience and we have not yet gotten our chicks but we have pretty much completed the coop, but im wondering ,we live on half acre that is fenced on both sides and some in the front but the back of the yard is not fenced at all and is open to a big field. now im wondering do chicken s wonder or do they tend to stay close to the coop. they would be locked up at night but im debating wether to build a run or not, the coop ended up costing more then i wanted and i'm not sure if i want to spend the extra money for a run. and if so, any inexpensive suggestions for a run?? also this may sound stupid but i'm wondering if you do free range how do you get the birds to realize the coop is there home? and one more question, we live in central utah, i'm wondering to what temps do the birds do ok in???
