Hi A.!
Wow, it must be a challenge for all of you to have so much tension in your home and within your family! I'm so sorry that you are all going through this, and my heart really goes out to you and those beautiful boys!
The first thing I would do is let go of the notion that punishment is going to help the situation. Sure, the fighting might subside for awhile so that the boys don't have to give up something that they really want to do, but that isn't really getting to the heart of the matter, nor is it teaching them how to communicate with each other or consider each other's feelings.
First, I would ask myself, what kind of modelling do Dh and I do? When we have conflict, how is it resolved? Do *we* bicker? Does one person *win*? Do we work through things together, and come up with solutions that are consentual?
I notice that the more Dh and I model open communication, consideration for each other's feelings, and consentual conflict resolution, with the kids *and* with each other, the more I notice the kids following suit.
Next, I'm sure you have talked with each of your sons about their behavior and inquired about what is going on with them, and you said you don't buy it that they are 'just acting like boys.' Have you asked them *how* they are feeling, rather *why* they are behaving that way? Have you asked them *what* they each feel they need? Have you just listened without judgement, with no threats of punishment, no advice? Have you been able to show them empathy for what they are going through, and validated their feelings as being *okay*?
Sometimes just being heard and knowing that their feelings are okay, and that you are there to help, not to punish, can make a world of difference.
After you have thought this through, and perhaps done these things, then I would try sitting down with your whole family (including your little girl), and do the following:
1.)Have each boy state, beginning with 'I' (no 'you' statements...it sounds too much like blaming...starting with 'I' holds the person who is having the feeling accountable for his own feelings), how he feels (instead of "when *you* do 'x' it *makes* me so mad!", have them try "I feel mad when I am trying to play 'x' and there isn't enough space" - a very vague example, but I don't really know your boys enough to get more specific)
2.)Have each boy start with 'I', and state what he needs (i.e. "I need my own room") during this phase, you are listening only, not judging the what they feel they need
3.)Practice empathy ("I'm sorry you are going through this", "wow, that must be really hard to deal with"), validation (maybe if you or Dh have siblings, you could tell them about some of the times when *you* had a hard time with your siblings...let them know it happens, that it is okay to have their feelings, and to express them), and reflective listening ("What I hear you saying is....")
5.)State, using 'I' messages, how you and the rest of the family are feeling about their actions...again, try not to fall into the trap of blaming! Simply state how you feel when you witness their actions towards each other, without accusing or judging. Then let them know that the family is suffering, and you'd like to work together to help them get what they need, so that you can all be together in harmony, not suffering.
4.)Have the whole family start brainstorming ideas on how to help each of the boys meet their needs...Be creative! No idea is a bad idea. Be sure just to jot down the ideas, even if it sounds totally impossible or unreasonable or irrational! Don't fall into judging the ideas...don't even comment on them, even if one of the ideas is to send one of them to some far away place, or to get their own house or something like that. Yell them out, and write them down, even the ones that sound ridiculous! Oh, and have fun while you do this!
5.)Go through the list, and try to figure out which ideas will:
a)will meet each of the boys needs, where they are at, right now, in this moment
b)will be possible
c)will also meet the needs of the family as a whole, and feel good to everyone.
The trick is to find solutions that cover all three of those steps.
***Yes! This is a lot of work and it takes time...but the more you are open to really listening without judgement, empathy and validation, *AND* are open to *all* of the possible solutions (and trust me, there are many, and you might be surprised by the creativity and depth of the solutions your children bring to the table...even your 5-year-old), the easier it gets. And a bonus is, the more you can do this in *all* your relationships, the more you will see your children doing it as well.***
I don't remember who recommended it, but I would second the motion of each boy having his own room...even if it is a small room. If that is not possible, then perhaps there is a place in the house where each of them can have a space that is just for them to 'get away'. I would also consider, if having separate bedrooms is not an option, if one of them could sleep somewhere else...or at least be able to when he is just feeling he needs to get away. Like I said, there are always so many options, we just have to be open and creative, and willing to think and act 'outside the box', without worrying what other people think or would do.
Finally, for more ideas, I would check out the following websites:

www.thework.com (The Work of Byron Katie)

***I strongly recommend checking into 'The Work' - when one is really open to trying it, it can be an amazing tool to explore where our thoughts and feelings come from, and how to effectively communicate and turn things around. I think it would be great for your family...and even your boys could do it!
Best wishes!
