Not all intact bucks showcase the typical behaviours and some do it more than others.
I have 2 intact Tan bucks and they are pretty different. Tesla is fairly hormonal, but it is mostly humping and circling. He is not aggressive, but doesn't like to be held (he would rather run around). He don't spray and and is pretty good with his litter box in the cage. The litter box does smell a bit when it is more dirty, but the smell is mostly in the box. He can smell a bit, especially around his bum. He is a very happy and social rabbit, always wanting to know what is going on and if people will pay attention to him.
Kraken is my other buck, he is also a Tan. He is more mellow than Tesla. He will hump a tunnel in the play pen and used to hump his bed. He doesn't spray either and is very good with the litter box in his cage. His box does not small as much, but can still have a bit if a buckish smell. He is also quite friendly, but is easier to handle and will be more comfortable being held for longer periods.
