The Moonshiner, are we to assume that these are your own rabbits and you have had them together for a long period of time and you never have had a problem with aggression?
Because what I am not seeing is a lot of droppings in these pictures. My rabbits poop as they eat, so if they actually were all there together eating the hay, I think I would see more bunny berries around with that many rabbits, even if you have just cleaned the area, there would even be some on top of the bale.
I am not doubting that anyone can put a bunch of rabbits together, especially juniors which looks like the majority in the pictures are, and they will not go into a biting frenzy immediately, but that it can and too often does happen that there is aggression.
