Backstory: I grew up having one female guinea at a time. My daughter and I decided we needed guinea pigs to love on, so almost a year ago, we got two guinea pigs from a pet store (we tried to adopt, but there weren't any available less than an hour away). They are brothers and are now about a year old. At the time, we assumed Mickey was probably the runt because he was so small compared to Donnie. They've gotten along and done well despite a shift in power.
Current behavior: Over the last couple of months, Mickey has become huge. It's obvious that he's been eating most of the food. Mickey seems to be taking his assertion of dominance to the extreme. Mickey has also started chasing, mounting, and nipping at Donnie ALL THE TIME. Mickey will not leave Donnie alone for more than a few minutes. Donnie seems to be fine with Mickey being dominant. He runs away from Mickey and doesn't appear to challenge him at all. I don't know what to do with Mickey.
What I've tried: We've had two water bottles and two food bowls in the same "kitchen" area for a long time. When Mickey started excessively mounting and chasing, I separated the food - one bottle and one bowl on each end. It seemed to help for a couple of days. When Mickey started nipping at Donnie, I occasionally put a divider between them to give Donnie a few minutes peace when Mickey seemed to be at his worse (only an hour or two). When the divider came down, they were fine. Today, Mickey has been in rare form. He will NOT leave Donnie alone at all. I welcome any suggestions for what to do!
