Is it normal for hamsters to run away from you when you try to hold them?

Im buying a hamster tommorrow. I have friends that have hamsters that they just put there hands in the cage and the hamsters come running to them… How do i get my hamster to do that?

How long does it take parakeets to settle down after you bring them home?

I bought 3 parakeets about 2 1/2 weeks ago. I then went back a week later and bought another female and she is very wild. The first three were begininng to settle down until I brought the 4th one home. Now they are all very skiddish. Will they ever settle down? I spend as much time as I can talking to them and singing to them. I have one that will sit on my shoulder and let me walk with her but the minute I sit down she flies off. Will they ever settle down?
