Here recently, since acquiring my cockatiel, I discovered that the abusive situation he was in included fouled water and only treats.
Since reading up on these birds and trolling the internet, That if I can, I will try to turn him over to pellets.
I'm not so confident about that tho. He's pretty picky and won't eat a variety of seeds let alone fresh fruits and veggies.
I worry that his habit will eventually harm him in the long run. I intend to get another cockatiel to keep him company since I work every day.
What I hope is to get a bird who is not afraid of me and will allow me to take it out of the cage and hand feed it. I'm pretty sure this will teach Jack to trust me and to try different forms of food....
