If you keep housing the two males together, you Will wake up to a deador nearly-dead rabbit in the cage. If you care about the two of them,which I'm sure you do, SEPARATE them IMMEDIATELY. Right Now! This hasgone on long enough. The weaker one must be completely stressed whenit's night time. That's probably the one who doesn't want to enter 'thelion's den' at night. Poor little guy. Would you want to have to fightfor your life night after night? You're worried about predators; thembeing together is like one predator on prey.
Don't let these rabbits stay in the same cage another night. Even if you have to put one in the bathroom for the night.
They're going to hurt each other at the very least, then there's bacterial worries, infections, etc.
Stop delaying. One more night could be their last and I'm sorry tosound cruel, but do you want their blood on your hands? It's unfair andirresponsible to keep putting them together. They aren't going tomagically get along. They're two males fighting for their 'warren',territory, control, and power.
If you have to find a breeder in your area, I'm sure one of them wouldbe willing to lend you a cage if they have one until you're able to getone yourself, or a shelter would, or just buy a portable animalcarrier. You're really playing with fire, and the death or severeinjury can be avoided by You.
