My EE is 4 months old and just within the last couple of weeks she starting bitting my arms and now legs. So was always the friendliest of my birds. She use to let me pick her up and was the first that came running when I'd go out to the run. She still eats out of my hand but then she bites my arm, not peck, but bites. I'm just curiouser why the change in temperament. Any suggesting will be appreciated.
