Worried about my new birds

Question
Hello, I recently bought 2 parakeets, about 1 week ago. No idea about the
age, I think one is a female (yellow/green) and the other one is a male (blue).
I am not sure if they are scared or bored. The are usually standing on the
perch and do nothing! They don't sing or make any noises and they seem to
be stressed out because they move their wings very often. I feel so bad! I was
told to cover them until they get used to the noises in the room, but for how
long should I do that? I was also told to put give them a bath once a week
because they love that but I don't want to scare them even more by putting
my hands inside their cage! The blue one seems more comfortable because
he plays sometimes (not often) with the mirror and bell they have in the cage
but the yellow one seems moody. The blue one tries to peck the feathers of
the other bird and the yellow one gets really mad. PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!

Answer
You might try seperating them to see if that calms them down a bit. Sometimes it just takes time to win their trust. Try leaving the cage door open while you work nearby to encourage them to come out on their own. Talk quietly to them and give them treats like millet. - At this age it's all about winning their trust.
