Okay so heres the deal. Lately one of my ducks (an 8 month old drake) has been acting very oddly. Every time I go to refill his water or food or do almost anything he tries to "nip" me and almost chases me around. He used to be the sweetest duck and would let me pet him and play with him but now all of the sudden he has turned into a very grouchy little guy. I just can't figure it out. Any help would be GREATLY appreciated -- I want my sweet duck back!
