I recently got 2 pekin ducks along with 6 chicks. They are all about 2 months old and are living in a fully enclosed run with coop access. The problem I am having is with the ducks being ducks and using all the water in a matter of hours and not leaving any for the chicks to drink (plus they are bigger and thus poop more and are messier in general). I want to eventually let them live cage free (at least during the day). So my question is, at what age can I do that (for the ducks)? Or is there some other way of not letting the ducks use the chicks drinking water that I'm not thinking of? They all get along well, but I need to solve this issue somehow. TIA.
