Our numbers fluctuate butup until aweek ago we had 17 rabbits and we were going through 100 lbsevery 3 weeks or so. I buy 2 - 50lb bags at a time. We buy two different types of Purina and mix them.
I have a large herd and several of them are flemish giants. I buy around 300 pounds every 2 weeks - sometimes its 250 pounds. A lot of it depends upon if I have nursing moms, etc.
