I rescued two Muscovy mix from our river and a full on Muscovy drake probably their dad. All 3 drakes I’d say being they are a mix they would probably be okay with either but I’d def get at least 3 females. No other drakes. My Muscovy drakes could not live with each other and it was many years of keeping them separated with their own females to keep the fighting from going on. Again just my 2 cents.
