Hi Sam and
to the forums!
I'm glad that Dawn and Finch are settling in well--those are lovely names and they sound like very sweet little birds
I do agree--at least a week for them to settle in, two weeks is best. During that time, speaking to them softly, reading to them a few times a day and just sitting by their cage helps to get them acquainted with your presence and voice helps, too.
Based on the progress you've made, I believe you can keep leaving your hand in the cage a little bit, without moving it, as you're changing things in the cage. Feeding millet is a bit too fast so far, because even if she'll willingly eat it, many budgies act very submissive and complacent for the first few days because they're terrified.
So I would take a tiny step back--keep doing what you're doing, but focus more on them getting to know you before you move your hand any closer or offer food
This ensures the bond you build with them will be a strong one
Meanwhile, be sure to read through the forum articles and "stickies" (threads "stuck" to the top of each subforum for easy reference) to ensure you're up to date on the very best of budgie care and practices
If you have any questions after doing so, please be sure to ask as we'd love to help!
I hope to see you around and we'd love to meet Dawn and Finch when you have time!
