I know many say not to have the ducklings go outside until late January, early February, but all the ducklings who are 8 & soon to be 6wks old have all their adults feathers. Can I start letting them outside on our deck for a few hours if the temps aren't to terribly cold since they have their adult feathers in?? I would not have them outside in extreme conditions, which will be in the next 24-48hrs. We are due for a monster of a snow storm. But other then that, when weather permits can I do that? And when should I claim it "safe" to put them with mom and dad? I will be putting them side/side in cages at night so they can get use to each other. But if they shouldn't or can't be outside even with adult feathers, why is that??
