Hi guys, our chicks are around 6 weeks old and later today I'm hoping to have their outdoor run finished up. Along with the run, they have a 16" tall area underneath the entire 8'x8' coop to hang out as well. Are they old enough to go outside and still understand at the end of the day how to go back in the coop? They aren't quite friendly enough to pet or pick up yet and if they decide to run from me and hide under the coop, its going to be a really crappy time chasing baby chickens.....
