We made him a playset, but he's scared of it haha. He's out of his cage a minimum of 2 hours a day.. usually 4 depending if i'm busy. The woman at he store said to get the smaller one or else he won't ever want to leave. (Which I don't believe, but whatever). He is on Vita Bird Cockatiel mix right now. Here's a picture of the playset:All great points already posted!
A $27 cage is Ok for going outside or travel or tthe Dr. Its a good price but min size.
Most important now is to get some natural wood perches. They have them quite resonale with one side clamp & they donlt have to go across the entirer cage just put them in various locations
They are better for the health of the feet.
You can shop around for a bigger cage. I have seen some even in the $100 range that are really nice.
Baby tiels can be clumbsy too so you have to watch for that.
I would recommend Higgins seed & Higgins Intune pellets. They are fruity & most birds like them.
It would be best to do a slow transition of the old food with new but as for seed I think just gove him the higgins as seed is easily switched but pellets are harder & he may not even ever have had pellets.
Higgins has Safflower gold which I think would be good for a tiel
Roudy bush is supposed to be good & Harrisons but Rio does not like them.
You can contact many co for samples.
