Disclaimer : I’m not a rabbit feeding expert. I was just getting into rabbits and learning, but decided they weren’t for me, so I sold the few I had.
I was under the impression that hay was more important for rabbits, and the pelleted feed was supposed to just be a supplement. I made sure my rabbits always had hay, and then I just gave them a measured small amount of pellets each day.
But I don’t know how that would work with a lot of rabbits. Probably still go through a lot of pellets that way. Plus, if you can’t get good alfalfa hay, it might not work. I don’t know if Timothy hay would be better or not?
