My Boar has been at it all week, he lives with his friend, he has been rumblestrutting, lurching, chinning, stopping other pig from eating, chattering teeth, nipping, pulling fur out, and chasing him around the whole cage, they are in a 6x2 c&c cage, they have garden time in a huge run nearly everyday, 2 or everything, separate feeding stations, other pig will constantly chase the other one away, same with the beds, he will just chase him and try to hump him, this has been going on for 2 weeks but getting slowly worse, last night i was home from 6.30 and went to bed at 11 and they were constant, didn't stop all night, I have separated them with a divider today and bully pig was biting the bars and going nuts, while the other pig was popcorning and happy, prior to this he has become very depressed and low, i have had them vet checked and both are in good health, should i seperate permanently? thanks for reading.
