You could take them off and use them. There are health benefits from them that you could look up and think about, here is an immediate use in recipes:

here is info on why the blueberries may be shriveling and also it is safe to eat them but once shriveled they suggest using them in cooking or baking

Yes, remove the shriveled berries and use them for jams or in baking.

Yes pick them off of the bush so no more plant energy goes into them. When you are making waffles or pancakes, throw in a handful in a saucepan and pour syrup in the pot to equal the amount you will use for the pancakes. While the pancakes are cooking let the syrup simmer and when the cakes are ready you have blueberry syrup. Blue berries freeze well. You can even freeze the shriveled ones in a ziploc bag for baking.

I leave mine for the birds to enjoy.... sometimes I get whole flocks that descend and devour them.

You can remove them and use the berries for baking or jelly. A blueberry loaf cake sounds good to me.

You can remove

Hi, Yes, no point in leaving them there.

Yes more will grow in its place and the energy will go to the rest of the plant instead of the dried beries

Removing them is better for the plants. Good luck!
