My goal is to get a pet duck to diaper and keep indoors. I also want to make it a therapy duck, going to hospitals, nursing homes and classes with kids that have disabilities. But I only want one. I would be with it always, so we could bond. If sex doesn't matter, then I could get this duck for really cheap from someone local. But if a male would be aggressive, then I should probably buy it from someone that could sex it (most likely metzer farms) and that will cost about $60 I'm thinking a Cayuga or Pekin. So...would a drake be aggressive during breeding season even if he doesn't have any other ducks to impress or get competetive with? I'm wondering if it would claim me as a mate, yikes!
