I feed my rabbits winter wheat fodder and timothy or orchard hay, depending on which one I get. The rabbits weight about 10lbs "ish" and I feed the full 5% of the body weight so about 8 oz. Some rabbits seem fine with that but there are a few that the spine feels a little spiky to me. What do I increase more of, hay or fodder? I try to keep fodder in there at all times for them but I am rarely successful at that.
