We got enough money back in our tax refund that I can finally get some ducks (YAY). I've been poring over everything I can find about making a secure shelter for them. We live in a rural area near a river and probably have every potential predator there is in the area (someone shot a bear that attacked the dogs in their yard less than 15 miles from us this weekend!) but I think the main ones we will need to worry about are foxes, skunks, dogs, weasels, hawks, eagles and owls. We also have pretty cold winters- it's not uncommon to see nights in the single digits for at least a month or so, and several feet of snow. I'm planning to get 10 Khaki Campbells. I thought a shelter about 4x5x4', with a hinged shed roof so we can access the inside easily, and about 8' square yard for when I can't let them out. I can't decide whether to let them free range or use a tractor during the day. For the yard, I was thinking of using 5' welded wire fencing, and sinking a foot of it underground to discourage digging predators, and more welded wire on top to protect from flying ones. We have a dog who I think can be trained to accept the ducks as part of the family, but she isn't outside at night- prefers to sleep by our bed- so she won't be out there to give an alarm or chase predators away.
If I use plywood for the sides and roof of the shelter, how thick should I go? Would 1/4" be good enough or should I go with 5/8 or even more? Will welded wire hold up ok or should I go with non-climb? or hardware cloth?
I used 1/2" plywood and the hardware cloth. Not sure where you live, but if you have coons or smaller animals like that, they can reach in and grab your birds.
