I spent some time out with the 48 FR we have (62 days old at the time) and was surprised to see some of the largest ones bullying the others, especially around the feeder. They would peck at them and drive them away. I added another feeder but the bullying persists. Have others observed this behavior? It means that some of the smaller birds in particular are picked on and have a difficult time feeding unless there are no other birds at the feeders.
