Hi so on May 5th I saved a baby mallard duckling that was being chased by a cat (had to be around 4 days old when I saved him) ever since then he imprinted on me and loves to be around me. He is starting to get his color in so I know it a boy but he paces back and forth in his cage. I know that means he is lonely but I can't get another duck for him since I know another male would make them fight and only 1 female isn't good either. He is fine with me but when my sister comes in his whole body vibrantes and he attacks her and it's only her. He doesn't do that to my dad, mom, other siblings just her! Everytime he attacks her she just pokes me and he stops. But what do you guys think? Will it be OK he is already almost 2 months so finding another duck his age will be hard cause they might bully each other and that would be rough. I moved rooms just today cause it's bigger for him. I also sleep in the room and before today he never paced. Could he be a little stressed out from the move?
