they can and will all be friendly. It depends on how much you work with them as poults. In all our years of turkeys we have only ever had one agressive turkey and that was a Royal Palm (not raised by us - we got him from another breeder). All our other Palms are very easy to get along with so that was just that one bird.
I have 3 Royal Palm hens...all big babies! Yesterday, there was a knock on my door and a neighbour, who had been walking by, asked if I had lost something. One of them was sitting next to her. She said when the turkey saw her, it started following her.
