I used to raise meat rabbits on pellets when I was a teen. Now I'm interested in getting started again, but am wondering if I can feed them hay only. We grow our own hay, you see, and it would be nice to have another set of creatures I can grow for meat on the hay. The hay is a mixed timothy, orchard grass, brome, red clover and lespedeza and some weeds of course- we don't spray the fields. I am feeding this to our cows right now and they are keeping their weight just fine with no grain. Would rabbits be OK on that diet too?
