This is chirpy, my first lovebird, he was raised with baby cockateils, handfeed and loved. Chirpy has no ideal that he is a lovebird LOL, his mate is a cockateil named Scruffy and yes he is a male also.Chirpy is also a peachface, he never bites anyone not even new people.
So I thought ummmm lets handfeed another lovebird also a peachface, but at the time I had no cockateils baby.Her name is Gizmo, hand raised she had lots of time with her human flock (mom and dad) she slept with her Teddy bear that she loves.spent a lot of time with dad (my hubby) he taught her to say GIZMO, as she jumped up as she said her name,she loves her ball she would stand on the ball and balance herself, while the ball was moving.Gizmo and her daddy got very bonded.
then it happened the bites, her cage was very close to her dad, nothing changed except her age she got older, her time to make eggs (no males around her but of course that don't stop anything) she attack her dad, she attacked if anyone came near her toys which was not in her cage.
We do have times that she will not bite at all, she very loving, wants her head to be scratch, and loved on.
This is what worked for us.
Get a spray bottle make sure it has the jet stream lol.(use only water)
When you get bit spray them just once and say NO BITE this will stop them for a moment and make them think.
They have a 3 second attention span, even playing with toys.
To get your bird out of his cage just open his door leave it open, its his choice but you can out fox him by putting millet outside his cage let him walk to it don't place it near the open door.
with Gizmo I have to have the spray bottle and place close to her cage, she will run to her tent yelling at me, and all I am doing is changing her food and water dish,she really hates that bottle, I don't have to use it just show her.this is some of the things we do.
Just don't rush your bird to hop on your hand it takes time.
