For the quail I may mock something up with a small bucket with a wooden disk with a dowel attached (plunger). I'll drill a hole in the lid for the dowel to go through. Should look like a butter churn. I might have to add some holes to the disk and some window screen or something - allow it to act like a strainer and allow microbes to move through the liquid above the disc and the liquid/feed mixture below the disk.
