I'm used to chickens, quail, and ducks. For those birds, we are often learning that we should provide a way that soaks up or dissipates bird poop. This includes having a caged bottom or straw in the coop / chicken house. However, for pigeons, so far from what I've seen, many people build the pigeon house with plywood floors...and then that's it. Smaller cages where the birds live, may have caged floors, but for what is being called a pigeon loft, it seems like there is no additional bedding material or lining needed in the loft. Is this because pigeons living in a loft, are often outside more than inside? Just wanted to clarify that point about pigeon poopage in their living quarters. Thanks!
