Hi, can anyone help we got a trio of boars last week they are 11 weeks old. They have been fine until last night and this moring two of them are fighting. One seems to be left out on his own in the cage whole the other two are in hideaways ect.. but the same one his own is the one who chatters his teeth and wags his bum while making a rumbling sound! Will this resolve? Shall we split them up? Help!
