I just got my cockatiel last night. Of course he is very nervous and scared, he nips anytime I put my hand in the cage to change his water and just say hi. He has come a long way since last night, climbing on his cage today, playing with toys, being more talkative and even flying out of the cage when I left the door open(I like to leave the door open so he knows he can come out, if he wants to). But he hasn't been eating at all, at least, not that I've seen. He picked at his pellet/seed mix I prepared but hasn't been actually eating. I got some spray millet today as a treat and he took to it immediately. I know it's more of a treat than a dietary supplement but is it okay to leave the millet stick in the cage for him to eat so he won't go hungry? I'm worried he isn't eating but he will eat the millet. Is this a good idea??
