I just got my new budgie yesterday and im concerned with how hes doing. When we first got him in his cage he flew around and got on his swing. After a few minutes he got on a perch and stayed there. He ate some millet but everytime i looked over he'd stop and look at me. After a while he then started breathing heavily. And slightly bobbing his tail. I was sleeping just a few minutes ago and woke up to him breathing heavier. As i watch him now hes twitching a little when he breathes and im worried for his health condition. I just would like to know if this is normal for them when they're adjusting to theyre new home or if i should go get him checked out. Ive searched the internet for answers and came really short so i dont know where else to go but to ask someone with experience. I dont want the little guy to be sick and i just got him.
