I used to take pets to animal education opportunities (formerly known as petting zoos). I was chair of that committee for years. We took our own friendly pets to schools, scouts, churches, a birthday party, nursing homes, grand openings etc. I animal per person so nothing got mobbed. Small animals could be put on beds and people came out of their shell when they touched them. They told us of their pets and it was great. We took dogs, cats, guinea pigs, rats, snakes & I had a chicken that you could hold upside-down like a baby. A person with a trailer sometimes came with a goat and mini horse. We did a fashion show with the dogs. Our organization helped place altered pets with all there shots in many nursing homes too.
If anyone has a little time even once a month talk to a nursing home and get your buds with friendly pets up to date on shots. Some of those people might be thrilled to just see your duck. You don't have to pass them around to everybody. You can hold and let them touch. Practice with friends first and don't overdo it. We stay about an hour.
