How can I make this feeder/waterer work?

[sheeshshe]

OK, my dad got me these rectangle thick plastic containers that held tools at his work. they are extremely sturdy and the plastic is thicker than a 5 gal bucket... I was looking at my coop (free coop in the process of fixing up) and thought that since I was being lazy and didn't feel like sawing out the 2 nest boxes that I didn't want, I could utilize that space to hold the rectangular bucket thingies. I would turn them into feeders and waterers or just 2 feeders or something.

Here are the 2 spaces which I would put these containers in...

now, they would hang off the end of the boxes about 1 1.2 inches.

1st question... what can I use as a tray for these to make it work as a feeder?

2nd question... do you think it is alright if I use their nightly perch and double it as a feeding perch? can I still put a poop board under that?


any suggestions? Thank you!
