Hello, I have ducklings that are about 4-5 five weeks old and am wondering if they are old enough to be let out with the adults. They are almost completely feathered out, still some fuzz on their backs, so do you think they will be ok during the cold nights outside yet, or wait longer? They currently go outside during the day and come inside at night. They would be in a coop with the adults, but it is not heated and it has been getting down in the 30's to 40's at night. And also, are they old enough (big enough) to be introduced into the flock and be able to defend themselves ok if any of the adults get pushy (I don't think they would hurt them but you never know) Any tips on helping them smoothly transition into the adult population? And lastly...when they are able to join the flock, what is the best way to teach them to go into the coop at night like the adult ducks do? I'm hoping to not have to chase them in there each night as we have a very large yard lol Thanks!!
