Hi, My lady Koffie is in heat at the moment. She's always been the dominant sow, but her and Dolly get on like a house on fire. However, this is the first time in 2 years that she's started mounting Dolly. Koffie's prowling and showing off and will not leave Dolly alone. Dolly seems positively scared of this new behaviour that her friend has never shown before. I feel very bad for Dolly. She literally can't escape the attention. After Koffie's been trying for about an hour, she gets tired and has a little nap, but immediately afterwards she'll start arguing and mounting again. Would it be wise for me to separate them for the time being, until Koffie's calmed down? Or would that just make things worse?
