My bag of food says to free feed kits. According to the book "Rabbits for Dummies," once they are eating hay and greens, cut back on the pellets to 1/2 cup per 5 pounds of body weight until they're 6 months old; when 6 months or older, cut back to 1/4 cup per 5 pounds of body weight. It also says timothy-based pellets is best. I know that alfalfa is fattening. My vet told me that they can live on
timothy hay. Hay is good for them as long as it isn't
alfalfa hay and give them as much hay as they want.
Congratulation on your new bunnies.
