You could try the Merrick Grain-Free line. Several of them are poultry-free. They are not too expensive. Merrick has also recently released a grain-free, poultry-free food under its more-affordable Whole Earth Farms line. I would recommend canned pumpkin or sweet potato to aid in the digestion, as well as pre- and pro-biotic (i.e. Healthy Essentials).
