I have 19 chicks and 6 ducks that are 5 and 4 weeks old. I orginally had them inside but moved them to the coop today(with heat lamp). The coop is a shed modified and attached to a chain link dog kennel. How long should I leave them inside the coop before letting them out into the kennel. Would two days to much or not enough? Will this be enough for them to establish that that is home and they should go in at night?
