I have 5 Muscovy hens and 1 drake (Boris). All of them are 1-2 years old. I am very new to scovies and I am in love with them! The issue I am having is the hens love to hang out on my roof and poor Boris has zero flying ability. He paces back and forth on the deck until his girls return to him. I was curious whether no drakes can fly? He is bigger than my largest mallard-type duck (even my jumbo pekin boy). The girls are so agile and it is awesome to watch the wing about. Boris gets extra angry when my mallard drake joins the girls on the roof!
