I got 6 of 9.5weeks old SS. They are staying outside since end of June. July 4th, I started free range. First week, they stayed around coop. It was hot week, everyday like almost or over 90F. Most of the time, they didn't come out from under the tree near the coop or stayed under the coop. Last a couple of days, we have cool weather with rain, they started roaming around pretty far. The coop is in the backyard. The land is butt to high way so back side is all fenced and tall bushes. The left side of yard is fenced in and right side is open. They started going left side of yard and yesterday they got in to neighbor's yard Good thing the dog wasn't out!! They didn't jump, they sneak in thru between fence.... Now they don't spend time around coop any more, they stay under the tree near my house. Then when sun is not out, they start roaming around to front yard!! Between coop and my house is more than 100ft. I don't think it's not like "I don't have space to play" yard. Whole yard fenced-in is only my choice for this situation ?? Or when they get old, get better to stay around coop???
