Would it be okay if I took my 2-2 1/2 week old chicks out in their run, just for a few minutes a day? THey are getting pretty restless in their brooder, and I thought if they could scratch, and dig and peck around, and really stretch their legs, and maybe their wings a bit, it might help them to be a little more calm in the brooder after I bring them in. So are they too young for quick outdoor time?
