I had 2 cockatiels.. bought at petaling street long time ago.. the shop cheated me that they will learn to talk. and call me to buy 2 cassets then on for them to hear.. but it doesnt work.
Everyday i let them out and fly around the house. but its a hard time bringing them back.. i had the cage opened... they sometimes will go back sometimes wont. when i try to grab them .. they bit me till my flesh is seen and blood ozzing out.

Later 1 died.. dunoe why. Soon another 1 died.
