That is weird, mine like cherry tomatoes and anything they can swallow whole and is red like strawberries and raspberries. They certainly are pickier than chickens.
My turkeys love tomatoes and cucumber slices. It's really about what they get used to when they are younger. Mine get really excited about and sounds of construction too, and I find mine to be a gang of hoodlums, I would never call mine sweet, they are too mischievous and troublemakers.
