Bullying..

So I made a post before about bullying. Cause I have 3 bunnies and my female have always been the more dominant one and I got told a bit of dominance chasing now and then is normal. But yh, now one of my males started to grunt and lunge out on my other male.. It doesn’t escalate or anything. But he have been doing this for over a week now and I haven’t separated them. Since my other male doesn’t seem stressed or anything like that. He’s not scared to walk over to him or anything either, and I just really wanna avoid separating them. I know he probably just wanna show dominance, but why now?? Everything has been great up until now. They have been bonded since April last year I think.. I have been trying to bond them a bit 1-1 in my bathroom, but it doesn’t seem to help. He’s still grunting at him and lunging out. I’m just scared that if I separate them, my females bond will break to one of them and I really wanna avoid that, since she’s usually the dominant one
