I'm looking to get 2 either duck or Goose but can't decide or maybe 1 of each as a indoor/outdoor pet... which is more friendly even dog like if possible? I read Pekin were great as pets and sociable. Can I keep 1 duck and 1 goose together.. Also which is better 2 males or 2 females? I'm looking for calm, friendly and loving bird non agressive!! Any ideas and tips would be great Thanks!
