Someobody near me is selling 2 week Mandarins. I have Pekins, Muscovies and some young Runners. How well will they interact? I do have a large covered pen and everyone is allowed out to free range when I'm around to supervise. I understand it's advisable to clip the Mandarins' wings. How well do they do in winter? And if I'm lucky enough to get a pair, does that mean the drake won't be eyeing my other females? Any tips on sexing at that age? And any general info you have would be helpful.
