Lentils & split peas can be fed raw with no ill effect. They are some of the few legumes with low levels of the trypsin (?) inhibitor. Peas are regularly fed raw to pigeons in pigeon grain mix. I have fed both with no problem. If you google lentils & peas, you can read the literature on poultry feeding.
