This is probably an easy one. Most people figure that strawberries are an okay fruit to feed, and they are! There’s nothing special about this fruit, but it needs to go on the “okay” list. The greens are fine to feed so you can simply chop them and feed. The small seeds on the outside are fine, they will not hurt your gliders.
Note: We often purchase these in the frozen foods section. If you purchase fresh, you will need to feed them within a short period of time. Frozen strawberries are healthy, provided they are purchased without additives.
