I need help. Oreo just turned one and decided to challenge everyone. This used to be the ranking, Rocky the top pig, Cookie the middle pig and Oreo the bottom pig. Now Oreo would rumble at Rocky but nothing more than that. He's been chasing and nipping at Cookie. I've inspected Cookie and don't see any bite marks, so I haven't separate them. Cookie is terrified of Oreo, he's been whimpering whenever Oreo gets near him. Then he would run as fast as he can away from Oreo and Oreo would chase him.
I forgot to mention, Oreo and Cookie are litter mates I got from Craigslist back in Jan. They have never fought. They are about 1 year old now (based on the previous owner, they were born in November 2008). Rocky is 2 years old, adopted on August 1, 2009. He took the leader role and Oreo used to be terrified of him.
They're all living in a 2x6 cage. I don't have any pigloo that would block them in. All my hideys are towel tents, fleece tents, or foot stools.
You can see the latest cage here:
I've recently added a ramp down to floor time. This might have caused the issue. The ramp has taken about 6"x14" of floor space from the main floor to get down to the level that leads to floor time.
I'm thinking about changing the cage to 3x5 with 2x2 hay loft. Will that help?
Now they have two 1x2 haylofts, would it help if I add another hay area?
