I dont know if they will fight each other but they will fight with chickens. My ducks and Chickens fight all of the time. Kind of reminds me of Westside Story, each gang with their own territory. The ducks free range all day and the chickens free range off and on all day with times rotating thru the 3 different coops. And who wins every time THE DUCKS....our drakes will defend "their"territory every time and even if the chickens get too close they will let the roosters have it......no one gets hurt and it's kind of a hoot to watch, very intresting observing the birds body language....our drakes do not seem to fight with each other and seem to share the females equally nor do they fight among themselves......

ok thanks. I know I have 1 boy muscovie and we have some more that are littlr babies and I think one of those are a boy. But, I was wondering if a mallard boy and a muscovie boy would fight because I saw them the other day flapping their wings at one another and pecking (not hard) at each other. Maybe they were just playing. Thanks Genny

I have two groups of three ducks....one from this year and one from last year. No, they do not "mix" but since they occupy essentially the same space there is some dissent in the ranks from time to time. Each group has two males and one female. One group is a pair of rouens and a male crested saxony and the other has a pair of cayugas and a male Swedish blue.

Their "fights" usually just entails some chasing and wing flapping no real bodily harm.

One of the drakes (males) has a limp and he is sexually molested by the drakes from the other group from time to time. That really ticks me off so I make it a practice to chase them off when I see it happening. LOL They have gotten so "tuned in" to my intrusions that now I just yell at them and they run, quacking away.
