I just brought a new budgie on Tuesday, He's a baby(7 weeks old). Once I had put him in his new cage I noticed he was opening his beak a little. I wasn't sure if this was due to stress or not so I left him. It's now Friday, he's been eating, chirping, flying and sitting on our fingers. He becomes fluffy when he's on our fingers and is comfortable enough to clean himself on us. However I've now noticed that he's opening his beak wider and sort of sticks his tounge out. It kind of looks like he's gagging a little. I've also noticed his blinking is a little out. On his right side he sometimes keeps his eye shut or closes it more. He hasn't been very sleepy and isn't fluffy all the time and there is no signs of tail bobbing. He seems happy however i know what I have pointed out are signs of sickness and am not sure whether these may be due to stress from moving homes or whether I should take him to the vet. He is getting more comfortable everyday and has started to dip his head into his water bowl. I don't know whether he's drinking it or not so I'm unsure 0on whether him lifting his beak could be dehydration.
