How can I get my male cockatiel to be nice How can I train him What techniques do I have to do

I have 4 cockatiels. One is a male and the other 3 are females. He is nice to 2 of them, but he is very aggressive towards the pied female. Whenever I try to take him out he tries to bite me.

I had a male who was VERY dominant, first one way to get a male cockatiel to be nice, and more trainable, is to have his wings clipped. that way he knows he has to depend on you.

Next. NEVER invaide their space..I NEVER stick my hand in their cage. unless they are not in it and i am cleaning it.

It is natural for the birds to try to bite you that is their safe space.

Heres what I did.. Open the cage. place millet on top of the cage, and let them see it.. cockatiels LOVE millet let them taste it, and they will be curious and wander up on top to eat it.. Your bird needs to be taught that you are a friend, spend time playing with him without trying to pick him up, Birds love to play peek a boo~~ at least mine do! spend time offering treats, again without trying to pick him up.

once he starts being a bit friendlier with you, start trying to teach him to "step up" every time you do this though you should offer him a treat.Every time he will come to you without biting praise him and reward him. Birds are so smart, he will get it. try scratching in an upwards motion on the back of his neck, even with his orange cheeks, they love it! (not all birds take right to this, you may have to do it a couple times for him to realize he likes it).
