My formerly "feral" fledgling pigeon is now eating peas and corn out of a dish. He doesn't like the corn so much. What should I start adding? What brand of overall mix is good to start working towards? Do pigeons and doves need special grit? No pet store or feed store here sells anything for pigeons/doves and small chicken/quail grit is hard to find but might be possible. Having only 1 pigeon buying lots of bulk grain bags isn't the most efficient and buying smaller quantities is just as expensive because then I have to go human grade.
