The pellets here are made specifically for rabbits & alfalfa hay pellets for them until they are full grown, so I'm hoping what you can get should be all right. They should be without nuts. Can you ask wherever you got the bunnies from where they get their pellets? You might have to use the same thing & add the nutrients that is in alfalfa hay that is not in grass pellets. If you can't find alfalfa pellets, can you find alfalfa hay? If so, feed non-alfalfa pellets, and mix the hay so it's 3/4 grass & 1/4 alfalfa. Clover hay is the only other kind of hay I know of that has as much calcium as alfalfa does. Both alfalfa & clover are legumes, so any other hay made from legumes should work ok if it's an edible plant.
