However, not only for birds - other small animals can also use it.. And not only the feeder - if you pour water there, there will be a drinker. The point is that it can be an automatic feeder, and the feed will enter it as it is consumed.
You can do this, as the craftsmen say, very quickly and easily. Of course, for three dozen chickens this is unacceptable, but a few layers will be satisfied. More precisely, the owners will be satisfied that the feed does not roll around the entire territory of the cottage. It will not be possible to stamp on it, and ducklings will not be able to swim in such a drinker, because everything is elevated above the ground. Why not take on the idea itself, perfecting it for your own needs?
