First and Second Day
The first rule is to never work with a bird inside his cage especially Lovebirds. So take your lovebird out of its cage.
It’s going to be hard to approach him at the beginning; he will fly away from you even if you put your hand close to the cage.
Tip: Use a perch, it’s easier.
Once you do get him out of the cage, for the first two days, just keep communicating and talking to him, give him some confidence, and play some lovebirds songs, he will start singing right away. Let him get used to your voice and the time outside the cage.
Repeat this 3-5 times a day for 10-20 minutes in the first two days.
Once your lovebird accepts you, and you get some trust from him in the first two days, you can start. Try to put him gently on his head or cheek, lovebirds love being scratched.
Repeat this 3-5 times for 10 to15 minutes.
Now you should’ve reached the stage where you have gained the trust of your lovebird; it should be so comfortable sitting and eating on your hand, now you can train them to do step-up: Push your finger slowly and gently against the bird’s lower chest, right above his legs. Reward the bird’s achievements. The Lovebird will learn to associate hand = food.
Repeat 2-3 times for 10-15 minutes each time.
Don’t be surprised if your lovebird on the fifth day starts to fly to you, in fact; he will start flying to you.
