So I found these Drain away trays on Ebay and they are awesome. I have them sitting on top of 3 4x4 blocks on top of a 4 wheel planter roller. I put the blocks under the trays so I could get a decent size pail under the drip spout. I screwed the blocks to the roller from underneath. Then I drilled 2 holes on the bottom of the plastic trays and then zipped tied the tray to the roller and it's perfect. Now about a half an hour after I feed them I come out and grab one pail at a time and pour it down the drain.
