hey! so I have two parakeets and I've had one for around five years and the other for maybe three? they usually cant wait to leave their cage and fly around but recently every time we open it they just stay in it. They don't fluff up or anything and they don't look particularly sick. Just kind of tired. The last time they went out is a few days ago.
My family recently went on vacation for a week and we left the cage door open for them as we do every time we go on vacation. Do you think it could be the heat? are they both sick? i'm so worried
EDIT: one left the cage and then after like an hour the other one followed. Sky, the second one to follow seems to have trouble flying and his wings shake and droop. Is it possible that he injured himself?
