My neighbor is gone flagging between Mon-Fri. and I'm the animal sitter and garden keeper D:

This is what I've come up with to keep her rabbits cool.

The night before take 24oz water bottles (filled with water) and freeze them. When it starts getting uncomfortably hot outside you can stick them in the hutch. They'll stuggle up to the bottles to keep cool!! Also, even tho the hutch is on the south east side, I'm still sliding a piece of plywood in front for extra shade in the afternoon that's about 13" from the doors..so it's not completely dark and air can still circulate.
