I have a cockatiel pair for 3 months now. The female comes to me whenever she wishes. Climbs on my head, sings to me but the male is still so scared of everyone and everything. I have tried bonding with him but nothing seems to work. Sometimes he will eat feom my hand and the next second he will get extremely scared of what he just did. How can i bond with him? Also they seem to hate their cage and do not consider it their home. My budgies will go back to their cage but cockatiel prefer to sleep outside whenever they get chance. How can i make them understand that their cage is their home?
