I raised a single mallard with two my two female chickens since they were 2 weeks old. They are now 20 weeks and I have recently discovered that he is a male. He likes to hang out with the chickens, I think he thinks he's one of them, but goes down by our pond and hangs out by himself. He appears lonely. I'm also worried, because at night they are housed together, that he may injure one of my chickens trying to mate with them. I want to get a second so that he is not lonely but I don't want baby ducks. Would a second male duck be an option? That way I can house them separately without him being alone. Do I need a female to make him happy? Please help!
