Noticed Sunday my little guy Thor was not very active and had his feathers fluffed out. Thought maybe it was do to the cold front coming in. Checked on him yesterday still the same so I picked him up to have a close look at him and he has NO meat on him. Brought him inside, gave him wormer as a precaution and feed as he wishes. His crop was large and hard but gave him some olive oil/buttermilk soaked bread which he devoured. I massaged his crop a little while afterwards and it dramactially went down. His poo is slightly runny from time to time but not everytime or severe. He eats and drinks at what appears to be a normal rate but he literally is skin and bones. What should I for my liitle guy?
