how many females per male they need so that they don't fight? are drakes like roosters?
I dont put females to males, i let the girls decide who to go with, now i do have more females than males but i dont have a system of how many females should go to males, but i would recommend 2 females to 1 male in most cases
I have two drakes and they have never ever been aggressive towards me they are a bit shy but that's because they were pretty completely feral when I got them so their like extremely tame compared to their younger selves.But I also have many roosters and some roosters do turn out to be aggressive while others remain very sweet.So it just depends but your possible drake has a lot of potential as being a very fun pet and also even if this one is a bit nippy all birds are different and have their own personalities and quirks.I have a goose that's extremely nippy and loud while her sister is extremely shy and a lot more stand offish and they were raised exactly the same.Hope this helps.
