well, I had the top of a indoor cage in the run yesterday with the 2 new sows in there, well they had been in it all afternoon and i had seen no aggression toward each group so i thought yes lets do it, so i opened the top and just undid the front opening of the cage open, closed the lid on the run and went and sat on the step to watch, well they all came out Jaffa in front then rusty then twigglet and so on all nose to bum and walked straight into the cage in the run :o there was no stopping to look they just seem to know it was open, they all walked in had a sniff around and then all of them with the new girls at the back walked out and started grazing,
I think it is amazing and for once i wish i had more pigs to see if the same dominance apply to a large herd , like it does with wolves with the pecking order and herd/pack instinct
who has a large herd free range? of 12 or more pigs?
