Mine were a little late this year too. I’m on the other side of the mountains from you.(NC WV) I used to put up my feeders as soon as I saw one. A dominant male would set up camp and chase away any hummers that would come near. Last year I waited three weeksw after I saw my first to set them out. It became like the Battle of Britain with as many as 8 birds at each feeder at dawn and dusk.
Same results this year. Only problem is that I have to refill both feeders daily.
LOL! We put up two feeders this year, to try and calm down the warfare. They sure do like to fight!
