I have read the guides in the behaviour section, and gone through quite a few threads, but I still don't know if Bianca's rumblestrutting is excessive. At around 2 1/2 months she had what I can only presume to be a really strong season (isn't that a bit young?) and she has been rumblestrutting ever since. They are 5.5 - 6 months now. Is it usual for a teenage sow to be asserting her dominance like this, so frequently throughout the day every day? We had thought Ophelia to be the dominant one and so I still tend to read Bianca's rumblestrutting as show. So in spite of Bianca's behaviour, it isn't clear to us who is boss -- with Ophelia giving hard nips to Bianca's ear, pushing her chin up; Bianca blocking the ramp or, sometimes it would seem, the sleeping area and rumblestrutting rumblestrutting rumblestrutting. For the most part Ophelia just ignores it, though I have heard a few submissive squeaks recently. There doesn't seem to be any overt aggression or confrontation (as is suggested in the behavioural guide re hormonal teenagers) and they do seem to coexist and even share. For example, when Ophelia neared the hay tray which Bianca was occupying, Bianca rumblestrutted at her, then a few moments later got out and Ophelia hopped in. When there is also mounting (either one of them), that is when I read it as one or the other being in season, although Ophelia's are far less pronounced. It just bothers me that Bianca rumblestruts so much and that I haven't witnessed any signs of affection. 'Co-existing' describes it.
