A few things I would like to add. If you are using a syringe, make sure to change sides to avoid a crooked beak.
Also it would be an idea to put a damp wash cloth under the towel at each feeding. The heat lamp you are using is very good for chickens and sick parrots, but a little too dry for a baby parrot. Maybe you would be better off with a lid with holes in it. That way the heat from the lamp is not as direct and drying as now.
Please also measure his weight every morning before his first feed. Be sure he is gaining weight every day. A good idea is to write it down and then calculate the percentage of weight gain. It should be relatively steady. If he suddenly differs, you have a faster chance at doing something about it.
The thickness of the formula has a great effect on the babys weight gain. If the weight does not rise steady, try a slightly thicker formula, but be sure not to make it too thick, as this will cause the baby to not properly empty the crop.
When I hand rear parrots I use syringes. I use the inside of my wrist to feel the temperature of the formula. It takes some training, but it's faster, than a thermometer. Also please recheck temperature for each bite. I find the formula cools quite rapidly. I use a cup of boiling water to reheat the formula during feeding (I usually also have more than one bird at a time). When the syringe has reheated, make sure to take in some air in the syringe and shake it well to avoid hot spots in the formula.
If you are sure, that all the parameters are correct and the baby still refuses formula, I mix some coconut milk with their formula. This usually makes them gulp it right down
Please update us of your babys progress.
