While cleaning out the bird cages at work (PetSmart) last Wednesday, I found the sweetest little budgie ever. it did not mind being picked up and sat on my hand while all of the other birds flew around like crazy. i immediately knew i needed to bring the baby home with me, and took him to the back to hold for myself until the day after Christmas, to give myself time to clean out my old cockateil cage. I brought him home the day after Christmas (4 days ago) and waited until yesterday to handle him at all. he acted exactly like at the store, allowing me to pick him up and hold him on my hand and even on my shoulder for a bit (about 30 min) before taking off and flying around the room. once he landed he let me lift him right back up and sat with me a little longer before going back into his cage. he has been eating well and as far as i can see, drinking well also. he has been puffed up for most of the time he has been home and has been sneezing some, which is starting to concern me. the room he is in tends to get cold, so i am working on getting it to a higher stable temp. I have never seen one this calm come through our store and it makes me worry that he was sent to us too young, (something our distributors are notorious for) and does not yet fear unknown objects, or that he is sick and just does not want to put in the effort to avoid handling. He has been communicating with the Quaker we have in the other room, but does not seem to climb or play. Do you all think he is just adjusting or should i look into taking him to the vet?
