It consists of 5 oats, 2 boss, 1 pumpkin seed. Every mix of that gets two bird seed on top.
The oats is for energy, BOSS (black oil sunflower seed) adds shine to their coats and energy, the pumpkin is a natural dewormer. The bird seed is just there to provide variety.
I make a big batch at a time. The rabbits LOVE this grain mix and clean up every time. If they don't dive for their bowls I start to wonder if something is wrong somewhere....
A note about pumpkin seeds:
Pumpkin seeds are a natural wormer for rabbits.

They are used in many cultures as a natural treatment for tapeworms and other parasites.
Do note that rabbits housed in wire cages rarely need to be wormed.
Many people like to treat with Ivermectin if they think they have a worm problem with their rabbits, generally speaking though, Panacur will work better and quicker. Ivermectin has some nasty side-affects with rabbits and has been known to cause, blindness and other issues.
Worms in rabbits can come in on the hay, fresh grasses, contact with other rabbits and through mouse fecal matter.
