So I'm offering everything to my RF but it seems to only be interested in zucchini. I've tried everything lately - dried and fresh flowers, lettuce/chard/chicory/etc, dandelions, bananas, strawberries, egg, chicken, pre-made pellets - everything under the sun but it picks through the pile and seeks out the zucchini like a guided missile. Is this something they do? It's never done it before. In the past it has eaten everything put in front of it.
