When picking our NG eggs up from the breeder, she entered the pen with a pitchfork to protect herself. Ominous start! We hand-raised half & put the rest under a hen. The hand-raised ones became quite aggressive but we handled them & they stopped trying to rip our skin off & became jolly, inquisitive, tame birds. The hen-raised ones were much more docile. This year we hatched 3 eggs from another breeder. They're VERY confident and mean. Our gigantic turkey is terrified of them and they pecked his sister to death. They're great with us - so tame - but real bullies with the other birds. I wouldn't put them in with gentle breeds. Most from last year were killed by predators but the remaining cockerel is a beaut. He's a real wimp with us, and at the bottom of the pecking order, but likes to mate with chicks, and mates v roughly with hens. We call him the Norfolk Pervert. He really is magnificent though.
