Animation port to unity as fbx query

Hi guys I’m trying to make animations in blender then saving as fbx file for use in unity just made my first one it was terrible but made worse by the fact it didn’t transfer over to unity most of the animation.

Ok so basically its a archer character who is removing a bow from his back and arrow from a quiver. I had to go frame by frame matching the arrow and bow to the hands so they synced up but when i imported to unity the bow and arrow did not move at all while the limbs did there thing.

What do i need to do to get the objects in a scene to register there movement like my character does. In the blend file it shows them all moving as intended but in unity its a bust?

Any ideas? Please keep in mind im a total noob here so not to technical:D
