Use a stick.
While he is in the cage, hold a small stick and push it into his belly slowly and say “Up!” Let him sit there, in the cage, for awhile. Then move him back to where he was in the cage and get him off the stick. Reach in with your hand and feed him Millet on the branch. Repeat the stick routine.
His thoughts: Hmmm…whazzat? A Stick! I sit on those all day…I guess it is safe. That hand over there is scary…but…it is over there, not here on my end of the stick. So I’m safe, I think. OK, now I’m back on my perch…Hmmm…whazzat? Millet?!? I Lurve me Millet! Gimme!!! So that big hand provides me food…can’t be all that bad. Munchmunchmunch. A stick again? OK, it wasn’t so bad the last time.
The next day do the same thing with the stick. Get him totally comfortable with the stick inside the cage…the stick is his moving perch. Continue to feed him with Millet branches by hand as this gets him used to your hand being in his cage providing him food. After a few days of this (really, don’t rush it, you’ll just get frustrated if you have to start over building its trust), move him outside of the cage on the stick. Keep him near the entrance of the cage in case he gets freaked and wants to jump back in. Now feed him on the stick with Millet from your hand. Put him back in the cage, or, build a perch on the lip of the cage door (unless you have a drawbridge door on your cage) by attaching one of the thick ropes from pet stores for birds to the entrance somehow.
After a day or two of outside on-a-stick hand feeding, try to get him on your finger inside the cage. Just hold him there. Then put him back on his perch, feed him some Millet, then try the finger again. Do this a few times over a day or three. Then, carefully and with millet in your other hand, pull him from inside to outside the cage with the millet near his face. He won’t notice he’s on your finger, outside of the cage because he’s eating the gift of the gods. Progress from there. I just got mine to chill on my shoulder by using the “love the millet so much I don’t notice anything else” trick. I pushed him off my finger with the millet stick onto my shoulder and then let him eat until he was too full to move. He fell asleep while I was watching TV.
If he is outside the cage now, are you having to grab him to get him back in the cage? BAD if you are. You never want to grab the guy with your big, scary hands. Get him used to the stick and then when you want him back in the cage, use the stick, not your hands.
This is a great website on budgies that I use and got my budgie on my finger within a week using the stick trick. I’m now trying to pet the guy, but he still snaps at my fingers, but he is getting better all the time. I’m really liking this new pet.
