My options for feeding my rabbits are limited and pricey here. Only two places carry actual "rabbit pellets". One is Squallmart, the other is Gebos. Both only have small bags which cost almost as much as a 50 pound bag from the feed store. Only one feed store carries rabbit pellets but it's dusty and cheap and I've gotten more than one bag that had some mold in it. The other just tells me to feed them straight alfalfa pellets, which I've been doing but it's acidified their urine something fierce. I saw this fodder system in the FarmTek catalog and just drooled, but at $3000 for the smallest system, it's hardly feasible for 8-10 rabbits. HOWEVER.... I am going to see if I can build my own. I have an idea for a sort of self watering gutter system but for now I'm going way cheap until I see how the buns do on fodder over pellets. If it works the way I've figured, I should be able to ditch the pellets and just feed the fodder and dry hay. Got it started, and so far so good using winter wheat, gallon water jugs, and a greenhouse flat.
