Hi new friends, i am new here. i know practically nothing about having ducks. i'm wanting to get ducks to help me control the slugs in the yard. may i request help on the following: 1 - get ducklings or adult ducks? I just saw a posting on CL for a small flock of KC ducks. i thought adult will be effective right away in slug control and at the same time, i can enjoy the eggs. 2. how do i keep the ducks in a particular area at a time? do they fly? what kind of 'pen' is needed? is there such a thing? thanks in advance.
