We penned in a large section of our yard with chicken wire, and built a box with their feed and a heat lamp inside, about 3' x 6'. Water is just outside, but I have enough room for the water inside the "porch" of their house. I'm still trying to decide if I should lock them in it at night or leave it open? I locked them in last night, their first night out. I woke up at 3:00 am and couldn't go back to sleep! I'm a worry wort.
As far as predators, I know we have some nearby skunks, and my neighbor said she has seen possums, but I've never seen any. There are a couple large dogs that come up from down the hill below us, but my yard is fenced off. I'm sure possums could get into the yard, not sure about thru the chicken wire. I have 2 indoor dogs that use a doggie door to go out whenever they want, but they sleep inside, usually pretty soundly. Should I lock the ducks up at night?
