Hi, I am wondering if it is safe to use Barley straw in water bowls of racing pigeons. I would buy the small bag that supposedly treats up to 500 gallons. The pigeon water is only 3 gallons. Would this overdose them on or have any negative effects. Thank you, Kevin
Barley straw is meant for the control of algae in large bodies of water, such as ponds. See http://extension.psu.edu/natural-resources/water/ponds/barley-straw. I wouldn't recommend using it in pigeon water bowls. If you are providing clean water on a regular basis, algae should not be an issue.
