I went inside and dug out the hummingbird feeder and hung it on the balcony. It holds 3 1/2 cups of water. I add about 1 cup of sugar and stir until it’s dissolved. You don’t need to add any food coloring. I have to lean out over the rail to hang it on the hook that my husband put into the eaves. To make it easier to attach it to the hook, he put a wire with a loop at the end, on the top of the feeder. Now, I can watch the hummingbirds from my office window.
