Our cockatiel is sick with an unknown illness, my mother refuses to take him to the vet because "he's an old bird" 
So i am hoping some of you may know what is wrong with him.
Symptoms
Head burried all day
wings slightly out
(crop?) under chin slightly larger than normal
general aura of not being ok.
his eyes do not seem to be swolen however.
today he seems to be a little better compared to last night but i am still worried, we have given him a heat lamp and raised the temperature during the night. Is there anything more i can do? i may give him a little cammomile tea for him to drink (read it in a book) please help
