So i have recently gotten my cockatiel (13/14 weeks old now) about 4 weeks ago. the breeder gave me seeds to have him on until i could switch it over slowly but life issues came up and i wasnt able to find the time to get any new seed to switch during that time so he had just been on the one from the breeder aswell as pellets and vegies (he eats both now). i'm just wondering if it would be okay to buy the new seed and since hes been eating pellets aswell for the past 4 weeks it would be okay to slowly give him some new seed without the previous seed there? not sure what to do thanks
