I just added a temporary run to the coop that I have been letting my 3 chickens (about 2 months old) run in when I am home. I didn't leave them at night or leave since it was 4 feet tall and was afraid they would jump it. However, I noticed that they barely made it half way up the side, so I went for a meeting this evening and didn't lock them up since I figured I'd be back by dark. However, the meeting ran late and to my big surprise I see one chicken sitting in a flower basket by my front entrance on the opposite side of the house! I pick it up (it's dark now) and put it back in the coop, and notice another one is gone. The run looks fine, but they must have jumped/flown over it (they were twice as athletic as I have seen them). I live in the city, but have a garden with many places to hide, so I am hoping the last one is hiding somewhere there, but my question is how far does chickens typically wander away from home if they get a chance? I feel bad that I didn't look better after them, but I guess there is always a chance she will come out from hiding in the morning and walk back to the coop area when she gets hungry... No more blue sky run for me!
