I love ducks,,, we had a really tame Indian Runner when i ws young, he was no trouble and very funny, we found him when he was a little yellow fluff ball and expected him to die but he did well. He was noisy and did make a mess, we didnt have a pond but he had 2 storage boxes filled with water which he was happy with,,,,,, We felt guilty he was on his own and were worried he was lonely and someone we know who has a huge pond lost one of theres so he went to live there
Oh and we did get rats while we had him
