Thanks for all of you nice people, I have them since 1 year and they are together in a cage size of 1 Square meter, with L shape wooden nest, they are located in a room on the roof, I have in that room as well Canary birds, I had the feeling that this room is not suitable place for breeding African Grey, whenever I go up to the room they escape and run away inside the nest and they will not come out unless I leave the room, I gave up and therefore I am planning to tame them and I need to know the steps which I should follow in order to do that, I hope I will find some body who can help me.
Thanks again for all of you.
