Oh @anniem, I am so jealous. I love hummingbirds but only have two of them, despite the fact that I have three feeding stations. One of them spends all its time chasing the other away from the feeders.
We had 4 or 5 of them, and one always chased the other away. We got another feeder, and it was better. When we got the deck painted, the feeders had to come down for about two weeks. When we put them back up there was a swarm! There must have been babies born while the deck was being worked on, a couple were big but many were tiny. I really like watching them. I took some photos but they just didn't show the crowd well.
