Since my drake got killed last week, the two girls have been acting quite a bit different. The Cayuga is now incredibly vocal. If she catches a glimpse of me in the window she quacks several times real loud; she also does this every time I come outside, if anyone else goes out, if someone pulls in the driveway, etc. She was never this vocal before. None of this bothers me. The thing that I am curious about is when I come out she will quack loudly several times, then come running up to me and when she gets to me she approaches me while bobbing her head up and down. This she never did to me before. Why does she do it? Does anyone know?
