I raise both mallard and pekin ducks, and they are great pets. They follow my wife and I around, especially when we are working in the gardens. We toss the weeds, bugs, slugs etc and the love it. I've learned how to get my ducks in a row.
Lol Quackers use to follow me all the time. Since going through her rebellious teenage phase its only when she wants to Lol.
My first recommendation would be to get a companion or two for your duck. They are social creatures, and want to be part of a flock.
When Quackers is set up outside I'm hoping to get at least one more that'll be the same age and a Muscovy.
For housing, some sort of dog house type building would work well. Get one big enough for a large dog breed, so you have plenty of room for the ducks. Something 3'x4' would be good for 3 ducks.
Funny you mention that I was actually thinking about that lol.
Since you live in a hot climate, you will want plenty of ventilation. If you have working windows on two sides, you can control the amount of fresh air easily. I would put a working door on it, so you can lock them up at night.
If the door is open all day and only closed at night, do you think I'll still need window's? She'll be only in the house if she decides to during the day and only locked up at night. There's always at least one person home and her house will be in our front yard right in front of big living room window. Plus we have dogs who are in and out all day. So she'll always be kept an eye on.
While you think you have only rats and roaches, I can assure you that you have more that you don't see. I thought the same thing until I put out a couple of motion sensor camera's around the coop - I have pictures of all sorts of critters and predators that I never see during the day.
Do you think I should put window's and put the hardware cloth on it so when it is hot I can keep at least one window open at night?
You will need to clean the dog house / coop out every so often, so make sure you can access it easily. Trying to clean it through the duck door won't work! Make the roof removable or at least hinged so you have easy access.
Do you think having a bottomless dog house, ontop of a piece of plywood which would be ontop of a pallet would be a good idea? Or would the hinged roof be better? Also what would you suggest for bedding? I was thinking of using Timothy hay.
My ducks use a ramp without issue. I did add 4" sides to the ramp, and that helps them from falling off it. They waddle, so a straight line is a bit of a challenge for them!
If I go with the pallet idea I think it'll be easier for her to go up since it won't be a steep ramp.
Ducks are very messy. They need access to water, and turn everything around it to mud. So plan for that when you decide where to place your pool, pond or waterer. Bark makes a good ground cover to avoid mud, but you have to make sure it drys out to avoid mold.
I don't plan on feeding her in her house. I'll probably feed her on our front porch so she won't make a muddy mess with her food lol. As for the pool/pond it'll be on the opposite side of the yard.
A kiddie pool or pre-formed pond can be perfect for the ducks. I have a 2 acre pond in my backyard, and my ducks prefer the kiddie pool instead! My mallards like to bath in a 2 gallon bowl.
Knowing my luck, if I do a pond Quackers will probably prefer a kiddie pool too lol.
Let us know how it goes. Take lots of pictures, we enjoy seeing them, and you can have your own album for quackers.
