I have two ducks, which I believe are a Pekin and a Buff Orpington, that live with my flock of chickens. They're all roughly 2 months old, give or take a couple of weeks and not free ranging - yet(I think they're still too young?). Anyhow, we have a creek in our yard that will serve the ducks as their swimming/bathing/watering hole but aside from their drinking/bill rinsing water, we haven't given them access to water they can bathe and swim in. Is this bad? Am I hurting or depriving them? And if so, can I let them free range so they can have access to the creek or are they still too young(I think they're about 2.5 months old)? Thank you in advance.
