How much do parakeets/canaries cost and which one is easier to take care of?

My sister and I want to get a pet birdbut we know nothing about the costs. We would like to get it from a pet store. We already have a cage. information please!!!!!!!!!!!!!!!!!!!!!!!!!
- yes i’m mean, get over it!!!

How should I care for my 2 month old and 2 yr old parakeets?

I recently became the proud owner of a rescued 2yr old parakeet and a 2 month old albino parakeet. The 2yr old seems to be comfortable in his new home. The 2month old however seems sad and does not want to eat. I just bought her from a pet store a few days ago. Could it be she’s just not used to her new home yet? Or did I make a mistake in having two parakeets with a big gap in their ages?

I’m concerned that she feels intimadated by the older parakeet.
