My juvenile pair of Black swans could care less about their Mazuri Waterfowl Feed so I'm trying to find alternatives for feeding. Can they eat fruit? I searched and searched and can't find any info on the subject. I have found they love the feeder goldfish and enjoy chasing them down in the water. I've been cutting some store bought cod fish up in pieces and they eat that too. Giving them lots of vegetable but seems some fruit would be in order. Are any of you feeding fruit to your swans? Thanks.
