Hi after some advice, we have 3 boars who were apparently from same litter. We got them aged 12weeks in aug,up to now other than the occasional minor scuffle have been no issues. About a week ago one of them seemed to be singled out by the other 2, they had a pet shop adequate but seemed to me too small outdoor house but constant access to a 10mx5m run with a few escape from each other hides, they were only shut up at night and still had options to get away if need be. Yesterday I moved them into a shed for winter again a reasonable size about 6ft by 4ft with loads more hideaways than outside and also a second level but I have come to them tonight and the bullied piggie had loads of nasty scratches on his back he seems to be smaller than other two, may have lost weight and was really withdrawn. Do I separate them? They have multiple water bottles hay access and other food so not sure how else I can stop the bully boys. I would have to bring the other one inside in a small cage (we have dog, a good dog but floor access may not be great) and he would be on his own? Any advice?
