I make my own hummingbird nectar (1 cup real cane sugar to 4 cups water brought to a boil). How do I add calcium to the nectar?
Female hummingbirds supplement their calcium by eating mineral dust and wood ash. They can also get their calcium from dirt, sand and fine grit particles. I am not sure if you can add mineral dust or wood ash to your hummingbird nectar. I would check at a pet store and see if they have either one of these you can add to your nectar. That would be the only way I could see you adding calcium to the nectar.
I would leave it as is, they usually supplement on their own.
The best way to add calcium is by using the water you have boiled eggs in as your nectar water. It has naturally added calcium from the eggs.
