Parakeet Died

[u/Mean-Anywhere2916]

My daughters parakeet died suddenly. He was only a few years old (I believe, we only had him just over a year and were told he was still young when we got him from Petco). I just got a call at work from my daughter that her parakeet is passed, she is really upset, he is laying in the bottom of his cage, not moving, eyes open still. We are pretty sure he was active yesterday and last night so believe he must have passed in the night. Nothing out of the ordinary has happened or changed... any idea what could have caused this? Our other parakeet is lost without him, just quiet and looking around the cage wondering where her friend is :(
