I have 8 week olds, the Delightful Dozen. They are a bit skittish of us humans, but if we sit still in the run they will come over and check us out. I expect that my birds will be out in the yard most evenings after I get home from work. They will have a few hours to scoot around the yard. The yard is large with 6 foot fences on all sides. So any suggestions on how and when to start letting them out to roam? Sunset here is close to 8pm and that has been when they put themselves to bed. Ideas appreciated!
