Cockatiel breeder or owner? Vet?

Bailee
Out of all these people someone must be able to help me. My cockatiel has been acting a little strange. Her moods are normal and she is eating and drinking normal. But her feathers have been puffed up for a few days (they will go down and puff back up very often) and she seems more sleepy than normal. According to google this is not good. I cant find a bird owner forum to get on and all my local avian vets are closed by time i get home and its been hard to make an appt! I know that when they're cold ir sleeping they'll get puffy, but what could be the reason for all day? Any advice from anyone??
