My pigeons are pooping in their water

[PioneerChicks]

I would do 4 inches. They like deep water, and it keeps cooler longer in the summer, if it's deep.

Okay, sounds good!

HI!
something that also happens is birds enjoy where their water bowl is placed a little too much, to prevent this, make sure to watch you birds, if you see them preferring a site over the water bowl, you have two options:
one- make the site less comfortable by changing the perch layout, lighting, etc.
two- more the watering apparatus to a less comfortable site.

Fascinating! I'll have to start watching where there is more droppings and where there is less!

If you really wanted to stick with the chick waterer you could always make a cover out of a small piece of plywood and some 2x4 pieces so that they poop on the plywood instead of the waterer but the empty milk jug with a hole would be just as easy. Either way

Oh, that will be a good back up, or separate waterer for new pigeons of I don't have another carton!
