We're still planning our coop and I was considering something similar to this bubbler fountain for providing water. I should explain that we live in the Sonoran desert and are already in triple digits and likely will remain so until September. Any standing water gets hot! The coop will be divided inside (see link) with hens on one side and doves, etc. on other side. The bubbler would be made so that we have an automatic water leveler attached (otherwise evaporation would be an issue). My thought process is that the the water would be getting refreshed because of the leveler and water would be cooler since it is moving.

Is this possible to provide water for 3-4 hens this way?
