Yesterday, on my way to school, I noticed a new goose in the pond on the way there, and saw that it looked like a domesticated breed. Today I got a closer look, and from what I could tell, it is either a Chinese goose or an African goose. It was swimming with two pekin ducks that someone also abandoned. My question is, is there any way I could catch the ducks or the goose? Its getting colder, and i wouldn't want to see them spend the winter freezing on the ice. Also, I have my own ducks, and I wouldn't want to bring any diseases in.
