We have a pair of Pekins. One boy, Arthur & one girl, Gwen Walter is loco ! He is a great mate for Gwen ! Watches her while she forages, let's her eat first, even will give up 1/2 a worm to her! BUT he won't stop attempting,to chase us & peck us. We have done all the holding down, flipping him over, keeping distance with a foam noodle, just to get their enclosure raked, water changed, fresh food, etc. Tellimg him no & tapping his beak. Nothing even with consistency ! What works best is music & picking him up & rocking him. He will go for this at least at minutes! He spreads his,one wing out & flaps it while I dance him around. Then he is great for a while. This approach happened whenever I was ready to just kick him, but did this.
