2 boars can be a problem as merci has said above.
How old are your boys?
Is there an age difference?
How did you set about introducing them?
How large is their cage?
I wouldn't say seperate them straight away, but you might need to go back to basics.
First off- check the Barmy4Boars website. They've got lots of "Boar Options" and read their "Our Boars".Their rescusers have matched up boars, not always sucessfully, sometimes they need to re-match them.
As a start off- I'd gve themneutral ground. A room without their smell.Preferably a room they haven't been in.
Empty everything out of their cage and clean it (Dettol is recommended) then fresh bedding.
And food.Lots of food. Seperate the pellets, water and veg so they can't crowd each other.
If you can (depending on how old they are) wash them to make them smell the same.
One of your boys might smell of female pig which would excite the other one.
Are they really squabbling? There will be mounting, rumblestrutting, 'heads up'.
There are signs to watch for (again Google) , but a ripped ear might be the result of a fight and hopefully nothing worse will happen.
My brothers are in a 4'x2' cage that last winter I had to seperate for night (they went out to their 'shed' every day) They had a nasty fight after a coriander binge.
This year, I've given them a box of hay, pellets, water bottle, veg. They're in the small bedroom <span class="italic">at night</span> with a duvet over.
They have the odd squabble but it's all noise.
