I put my hand in the cage and the budgies were fairly calm, they settled quickly and I moved my hand slowly toward them. They stayed calm so I pressed my finger against Yurio and he stepped up, Indie-Blue decided to join in and pushed Yurio up my wrist. I kept my hand still and they settled, after awhile of me speaking to them my arm started to hurt but they wouldn't move. I called my mum and she distracted them by tapping the bell of a nearby toy with the end of a pen, they jumped off to play and I started to slowly move my hand out. Yurio jumped back onto my finger but I was able to prompt him back onto a perch by moving my hand slowly underneath it, so I was free.
The babies are now flying round the cage and shouting at each-other. I think it went well.
I did the same as the first session and Yurio stepped up onto my finger and Indie-Blue pushed him onto my hand. I held my hand still and they settled, talking to each other and testing my hand with their beaks. After a few minutes both of my babies hopped off, this time Indie-Blue wouldn't let me take my hand away and kept hold of my finger with his other foot on the perch. I took my hand away once both birds were off and disinterested.
Same process, I was stuck for 20 minutes because Yurio decided to take a nap.
Your thread indicates 'it's been a week', so I'm assuming you mean a week since you got your birds?
Please be aware that new budgies can be a little passive when they are first bought into a home and so there may be some regression as they settle and they might be less reluctant to step up.
It might not happen, but if it doesn't, don't be disheartened.
It's generally recommended to leave the birds to settle a week before getting them used to your hand on you outside of the cage, inside on the second week and the third week would be when you start to introduce your hand into the cage.
As it seems to be going well, it's fine to continue. If they do have a regression, just take a step back to what they are comfortable with.
I was changing the food and water then my mum walked in and knocked the cage while my hand was inside it, this really spooked the budgies. Their now unsure and slightly spooked about my hand being inside the cage, honestly I'm not surprised. I'm going to take a few steps back with training and go back to just holding my hand near the bottom of the cage.
Session 1: I grabbed a handful of millet seeds from the bottom of the millet spray bag and held my hand in the cage by one of the perches, Yurio had a go eating from between my fingers then Indie-Blue jumped onto my hand from another perch and they both spooked. I removed my hand and cut the end off a millet spray, I held the millet at one end of a perch, Indie-Blue hopped up and started to eat from it. Yurio tried to climb past Indie-Blue to get to the millet so they started to argue then spooked again. I tried again but they ended up fighting over the place closer to the millet again so I decided to leave it for the day.
Session 2: I cut off the end of a millet spray and held it in the palm of my hand. I placed my hand by the perch the budgies were sat at, so the millet was between them. After a bit Yurio started to pick at the millet and Indie-Blue quickly joined in and they had a good go at it to the point they where picking bits out from between my fingers. I waited for an opportune moment to move my hand out and they didn't spook.
Session 3: I held the millet still on my palm with my thumb and placed my hand near where the birds were sat. Yurio was the first to start eating, it took less time today, but Indie-Blue continued to munch away long after Yurio had moved onto a different perch to preen in peace. There was more finger testing, not harsh nips, just "is this bit edible?" nips that tickled more than hurt so I just held my hand still.
Session 4: Indie-Blue was the first to eat this time. I was less careful at holding my hand still but the budgies weren't really interested and continued to much away at the millet, they didn't spook but did move to a different perch once they were done eating and started preening each-other. I think their starting to moult.
It's been awhile so I decided to make a new post instead of editing the last.
Session 1: I gave the budgies a couple of single millet balls, but Indie-Blue has turned into a little bully when it comes to treats so I had to move back to, holding the millet in my palm. They have started to gnaw at my fingers, I washed my hands before the session and they didn't pierce the skin, but I'm so use to rodent bites I can't tell how hard is too hard with the budgies. Yurio decided that sitting on my hand was the best way to avoid Indie-Blues harsh nips so I was stuck with my hand in the cage for way too long, my arm hurt so much.
It's been some time since I had my hand in their cage with the intentions of giving them a treat by hand. They've gotten fairly use to my hand being in their cage, changing the veg and wiping down the perches, and now tend to just sit on a perch away from what I'm doing and chirp to one-another. They still reluctantly take food from my hand, nibbling my fingers but not biting.
They have escaped a few times and right now the quickest, and less stressful, way to get them back in has been to grab them before they cause themselves injury. I hope to perch train them, but training them both at the same has proved very difficult.
