As for going outside, we started giving our chicks "yard time" for an hour a day after the first week... Supervised of course... After a couple weeks of this they got 1 hour unsupervised (ok, we peeped in on em, but they didnt know) ... By week 5 we let them spend the days outside, tho they didnt mingle with our grown chickens... But when it was time to go in for the night they go in just like everyone else... Here we are, week 8, everyone present and accounted for without incident
