Here's why:
* Territoriality: Bucks are highly territorial and will defend their space aggressively. If two bucks are housed together, they will likely fight over territory, food, and even females.
* Hormones: Testosterone levels play a significant role in aggression. Intact male rabbits (those that haven't been neutered) have higher testosterone levels, making them more prone to fighting.
* Social hierarchy: Even when neutered, male rabbits establish a social hierarchy. The dominant buck will often bully or fight with other bucks in the group to maintain his position.
Signs of fighting:
* Growling and hissing: Bucks may growl, hiss, or stamp their feet as a warning.
* Chasing and nipping: They may chase each other, nip at each other's fur, or try to mount each other.
* Biting and kicking: Severe fighting can involve biting, kicking, and even scratching, which can cause serious injuries.
Preventing fights:
* Neutering: Neutering significantly reduces aggression in male rabbits.
* Separate housing: It's best to house male rabbits individually, especially if they haven't been neutered.
* Slow introduction: If you want to introduce bucks, do it slowly and carefully, with a neutral area and plenty of space.
* Provide ample space: Make sure your rabbits have enough space to roam and avoid feeling crowded.
* Provide multiple resources: Provide multiple water bowls, food bowls, litter boxes, and hiding places to reduce competition.
If you see signs of fighting, separate the rabbits immediately. If there are injuries, consult a veterinarian.
