Would you consider using water from a fresh water fish tank to water your chickens? We have a 30gal heavily planted freshwater tank; we change the water every week. We test the water regularly and maintain it at 5-10 ppm nitrate, 0 nitrite, 0 ammonia, and 7.2ph. During the summer we put it on the garden, but have recently started thinking about giving it to the chickens. We have been giving the chickens a floating plant (like duckweed) when we clean it and it’s their favorite treat after mealworms. Thoughts?
