Hello-- I have Gizmo, a Cayuga x Khaki Cambell-Cayuga drake that was born in March. He practically hatched in my hands since I had to help him out of the shell. A few months ago he started to get aggressive towards my husband and me. He constantly chases us, bites and pulls on our skin, and wants us dead. He has made us bleed a little bit, too. We've tried putting him on his back, saying "No really loud, and tapping his beak firmly. He's only nice to us when we give him peas. As soon as the peas are gone, it's back to trying to kill us. What happened? Why is he like this? His duck mom and duck dad are sweet. Is there anything I can do?
