Very good question-I was thinking Kaytee seeds when I answered
Sorry for the late reply guys...
So Today, I go to the vet that I mentioned before, and Boi got checked up.
The Veterinarian said Boi has a healthy beak and lungs,
Boi also has good skin and feather condition too.
The main reason why Boi is refusing to eat probably because of these reasons:
1. Digestion / Bacterial problem so his appetite is gone
2. Bored with the food and afraid of the syringe
Stress is likely not the reason why Boi is sick because his behavior is normal, but His eating problem right now can cause Boi to weakened and stressed because of hunger.
The Veterinarian then gives Boi a vitamin injection to help his malnutrition, and hope that he would gain his appetite again.
I give the Pelet, Banana and Oat Meal after I went to vet and Boi's still same, He's still refusing. I don't know what to do anymore, This just too stressful for me.
Right now he's tired, and he seems to less talkative than yesterday. This is made me worry so much that this is getting more serious.
My question is ...
Should I force-feed him with Kaytee to save him?
Or Should I wait for the Vet home visit tomorrow morning?
btw Thank you so much guys for helping me so far
