I have 4 piggies all female that I have been trying to put together, right now they are in a side by side cage. 2 piggies per side. 3 piggies are older but still under a year and the other piggie is 1 month. I have tried to introduce them 2 times now. They are fine outside of the cage but as soon as i put them all together in the cage. 1 of my piggies wants to try to bite the little ones ears. It sounds like shes in pain so I separate them.and it looks like shes biting and pulling on it . It's a big cage 2 by 5 on each side. So when I take the divider out its 4 by 5
