Help !! 10 week old Pekin is extremely aggressive . We hatched him beginning of August 2011 and recently everytime anyone goes near , feeding, cleaning out ect he runs at them and pecks , hands feet whatever he can get hold of. He pecks really hard and won't let go and has drawn blood, he even chased my ten year old daughter. He's only tiny and can be picked up in only one hand but he packs one hell of a punch, those beaks as sharp. He used to be really tame He's even started to pick on his hatch mates all of them bigger than him. I have an existing flock of sussex, marans,(large fowl)wyandotte, orpington, polish (Bamtams) Hens and 2 Orpington and 1 polish cockerels. The plan was to introduce all the newbies at 12 weeks , (Sikies x 2 wyandotte x1 pekinx1 all hens and the evil one). What should i do stick him in with the big boys and girls early? or try taming him again ( is this even possible?) any suggestions ??
