Of our litter of 4, one has 2 bright blue eyes and doesn't seem to hear us calling. He stays asleep in the arc when the others come bounding out and I have to go rub him to wake him up. He is eating well but seems a bit different to the others. I think he is deaf. Anyone else had a deaf pig before?! I cant see this being a problem - as they are for eating not breeding from. He does love his tummy rubs...bless!
