I would take some and freeze in a single layer on a baking dish. when frozen, bag up and store in freezer for later. that'll at least take care of some of the bulk for another time. Otherwise...in a lot of recipes calling for blueberries, you can sub raspberries. Muffins, pancakes, quick breads...
how about a puree for serving over ice cream?
do you have a dehydrator? if you can make, strain, and dehydrate some puree, you can make a fruit leather.
jams/jellies
pies
little turnovers are good use for some too. What I do is get the already made crusts (2), cut each round into eight wedges (if you want bigger turn overs make less wedges). wet the edges with egg (good thing we have chickens huh?) and put on a dollop of pie filling (in this case made with raspberries.) fold the pie crust over and seal the edges using the egg. crimp real good with a fork. I usually get sixteen of these made. prick them with a fork. bake in the oven at about 375 for maybe 15 minutes, or longer depending on your oven, you are looking for a golden brown crust. then take a pound of confectionary sugar, mix in water a tablespoon at a time with an electric mixer until you get a nice, thick sugar glaze. pull the pies out of the oven, cool a little, and drizzle on the sugar glaze.
