I love hummingbirds!
I wish I would get more. I try to have at least two feeders out and I have tons of native plants with flowers to attract them. It is cheaper to make your own, just make sure you let it cool down a lot after making it (I put it in the fridge to cool down and keep it in there until I need to change it). It should be changed weekly if not earlier depending on how hot it gets. If it is in there too long, it will start to mold and you don't want those hummers getting sick!
FYI, you don't need to put red dye or food coloring in it. They will find it and I try to keep it as natural as possible since that's how the flower are producing it. I try to keep it chemical free.
If you want to make it yourself, bring 4 cups of water to boiling, add one cup of sugar and let it completely dissolve. Then let it sit enough to where you can pour it in a container and let it cool down in the fridge before putting it in the feeder.
