So my rabbits love the huge leaves that my mammoth sunflowers produce, and I'm just about to harvest 18 huge sunflower heads. From what I've read, BOSS is the go-to rabbit sunflower seed due to its oil content. Most other seeds are considered more of a protein/fat supplement. My rabbits are strictly for consumption, so would my mammoth seeds possibly serve my purposes at least as well as BOSS? I've also read to shell large sunflower seeds for rabbits. No way I'm taking the time to do that...anyone really think that it could be too much shell? I've been eating David sunflower seeds shell and all since my little league days, and I've never had a problem.
