My ducks do NOT like chickens. We have a fence that separates the ducks from the chickens and whenever a chicken walks by them, one will kinda shake the back of its neck and kinda puff up its neck (I am not sure if that's normal, it's like vibrating its neck...) and they all kinda "challenge" the chicken. And start quacking. It's taking the ducks FOREVER to learn how to get in the kiddie pool. I put this big flat rock near the pool to give them a 'boost' up and also a ramp....still no cluemy small dark KC has yet to figure it out while my other two some how manage to get in (when they get out they forget how they got in it seems like, they try but they can't)
They also still hate me, and can't figure out how to eat the peas I throw to them XDbut I love them anyways, they're fun to watch and super cute! (They are a lot more entertaining then my chickens lol)
My ducks and chickens hate each other, the other day they were fighting through the fence. Mine always do the head vibration thing when they get mad, I have no idea what it is though
