House quail?

You'd need to make some sort of diaper first, like you can get for chickens, but I'm sure it could be done. It may be demeaning for them though - quail are very image-conscious, so it'd probably be in their best interests to live in a cage or run or coop and not be house pets.

I sometimes bring a pair of my most tame ones into the conservatory for some treats, such as when family visit, but only after I've taped plastic sheets (opened out empty compost bags, etc) over the flooring. They have a great time. In just two hours they trash the place. I'm now convinced that quail were the inspiration behind Dr. Seuss' 'Thing one' and 'Thing 2'

 

I had a good laugh about Thing 1 and Thing 2. This is so right!!! Also please consider that their cuteness goes away pretty fast. Very soon it'll be just a bird and not a cute fluffy little ball.

 

Oh I love this idea haha! If you figure out the diaper let us know

I have some babies that LOVE to be pet (I posted a video on here a few hours ago of it haha) and I have two adult female I raised that I call "lap quail" because they're so chill, I can take them out they don't fly or run and I can pet them for hours all over, they seem to enjoy it and are sweet birds
