O.K...
I'll explain what happened.
Brego and Marilyn, their hutches were side by side outside, so they formed a bond..
Then I bought Maxine home, and I did the proper introduction between Marilyn & Maxine (in a large, neutral ground area etc etc) and they were fine together.
But then I put them both outside into Marilyn's hutch (freshly cleaned), & Maxine was sniffing Brego through the bars of the hutches and Brego was sniffing her, & it was like Marilyn was jealous & she was putting herself between the two so they couldnt smell each other. & then she started attacking Maxine.
The two girls haven't been housed together since.
Maxine wants the love and the attention from Marilyn, but Marilyn attacks her if she gets anywhere near her...
I have tried introducing them a few times. Each time Marilyn stays away from Maxine, but if Maxine comes too close, Marilyn attacks her...
But I have not housed either of the girls with the boy. The two girls are both way too young for breeding anyway...
ALL 3 of my pigs are housed alone :sad:
