Hello,
About a year ago I got two cockatiels. As much as I tried I couldn’t tame them. They have a big cage with many toys and a lot of room to move. They come out of their cage fruequently but they always stay on their cage.
I’ve managed to get one of them on my finger once and they both eat seeds out of my hand.
I really want to be able to tame them so they can come out of their cage and have more room to fly but for some reason it’s like they don’t want to be tamed.
I have another bird who is in her own cage but she is very aggressive and I have a similar issue with her.

Any advice?

Thank you
