We have 2 Pekin 11 mallard and 1 black swedish my Pekin's are about 4 1/2 weeks old and my mallard/black swedish are about 3 1/2 weeks old. I'm wondering at what age do you start letting them out to wander in the yard and I'm really wondering how in the heck do you get them back into the safety of their home at night or when I'm not around to supervise. I will have to walk them through my barn and up their little ramp to get them back into the barn every night but I am wondering with so many how do I do this? Also at what age do you think it's ok to keep the outside area available to them, right now I open it up to them during the day, it's attached to our barn and at night when it gets cooler I block off the door so they can not go outside and freeze. Sorry for so many questions I'm new to duckies if you can't tell
