so i just got a pinapple greencheek conure yesterday at a bird expo and hes 2 and a half months old but hasnt been weaned yet. the lady told me he eats formula once a day and showed me how to do it. i tried doing it two times today but he would not open his beak to take in the formula i dont know what to do. when the lady did it it seemed so easy he willingly opened his beak. hes old enough to start eating adult food so im trying to transition him but he still needs to eat formula until hes completely transitioned to eating adult food. help me please
