I have just adopted/fostered/ kidnapped two boars, they are pals but Pie is definitely the more dominant. I hear a variety of noises between them, (I have a piggiecam in the run) and just wondered if they are contented noises or angry ones? What should I expect to hear? Pie sometimes nudges Skewie and he jumps away. They seem happy together and show no signs of aggression, but I'm fascinated by the noises. (I am getting very little done in my life, as you can see...)
