Our small flock of 4 ducks (they are 4 weeks old: Black Swedish, Golden 300 Hybrid Layer, Khaki Campbell, and White Layer) LOVE to splash around and play in our salt water pool. Is drinking /playing in this, bad for them? Basically we let them out of their pen in the morning and they go straight to the pool, then a *while* later when they get bored they go off and free-range for the rest of the day. Sometimes we toss peas in for them to eat/splash around even more and have tons of fun. Is accidentaly drinking some while preening and eating their peas detrimental to their health?
