Is it possible to attach a 3d object to this and match its rotation? When I try, the whole 3d scene turns 2d and everything disappears.

Are you adding this behavior to 3dobject (not recommended) Or something else? Send a test project. Also look at dev console for errors.

Im just playing around and trying to make 3dobject rotate with the cube. There's many errors so I think I probably failed.

I am not exactly sure, how you want this scene to work, but it looks like the center of the chicken model is at the bottom, rather than the center of gravity. You can fix that in blender.
