My kids are now 10 weeks old. Yesterday I let them out for a few minutes while I did a deep clean of their coop and run and they loved it. However, I was out there with them the entire time. I am wondering at what age does everybody start to introduce their young chickens/new flock to the idea of free ranging? I am thinking of doing it for a couple of hours in the morning on nice days for their own personal enrichment, and to give the run a break from their digging/eating/pooping.
