I started handfeeding my lovebird at around 4 weeks and it was doing fine with me and I had put it into a separate cage from its parents so that it would trust me faster, but now its 7 weeks old and it does not let me even put my hand in its cage and bites finger alot whenever i do
can anyone please help me with this problem
Well, it is difficult to fully back-up, but it is fair to say that you have proven the point that removing the chick from the parents does not assure the chick will love you.
Some Basics:
It is never the fault of the Parrot!
It is always the fault of the Human!
Change your vantage point, and make changes to what you are doing!
Only good things happen when Humans are around!
One of the saving graces with most Parrots is that one can Start-Over, it just takes a bit longer...
