Garage aviary anon. I was mostly just looking into them as pets. I love how smart they are, and they just seem like such wonderful pets.
Pigeons are amazing pets. ^v^
Housing gets a lot more simple if you aren’t looking to breed.
You can just have a nest box available for each pigeon and they can free fly the garage.
If you don’t want eggs to hatch, the nest’s only criteria are that the pigeon fits comfortably. You can use a dog bowl, bunny litter pan, shoe box, wicker basket, even an open cat carrier stuffed with hay, pine straw, paper easter basket filling, anything light and thin that the pidge can arrange as it likes.
If you need to pen them up for any reason, wire dog crates are your friend! They are WAY cheaper than bird cages big enough to comfortably house a pigeon and they are super easy to modify.
