Would you know if it is OK to feed our lake swans floating fish food? Our feed store in Orlando Florida said that this food is perfectly OK for our Swans. He said that it is a little less then 30% protein and floats on the surface of the water better then pellets which will allow multiple swans to feed in a spread out proximity of each other. We do feed them lettuce and corn feed as well as they can feed algae at the bottom of the lake. Our grass has not grown well yet and we do have two cygnets who have survived this season so far. Thank you for your time. Donna
