I made the buns a cold weather mash today. I ground up sunflower seeds, cracked corn into a powderish like substance. I ground it because they wont eat it whole. They seemed to like it.
The breeder started mine on the BOSS so I can't take credit. They RUN over when I bring some out though and they are still shy around me. Perhaps now that yours have tried it they will go for whole ones.
BOSS is the one thing around here every animal eats, chickens, goats, ducks and rabbits. I certainly want to be growing some next year. I'd actually like to plant a sunflower forest if I can find enough space.
