It is best to house boas separately. That is always the best and safest......
That said.....I do keep some of my babies and some of my yearlings in little groups of 2 to 3 in large enclosures. I take them out and feed them in separate containers. After they eat, I rinse each animal with warm water for a few seconds...hopefully to wash away any rat smell on the snake. I have been doing this for a while now with no problems. Each of my little groups have been together for a long time. They all know that they have to come out to eat. They know the minute I put them in the "feeding containers" what is going on and that it's time to eat. It's amazing how a primitive reptilian brain can learn some things.
I only have a small collection and this works for *me*. It would be a lot of work for someone with a lot of snakes to do it this way. Housing them this way, I realize I could have an "eating incident" someday.....however, I think they know that they do not eat in their enclosures, they are well-fed, and they are rinsed off after eating. They do not connect their enclosure with food at all. If anything, they associate the door, and me, with eating because when feeding day gets close, their little internal clocks will have them hawking me at the door and I get the STARE until I take them out and feed them....too cute!!
My larger boas (2 and older) are all kept separately in their own enclosures and they are fed in the enclosures as well. My only little groups are the babies and yearlings.
You are right in your questioning about safety when breeding. I watch mine and remove the male when he is taking a break. That is when I offer them food (separately). Sometimes they eat and sometimes they don't. Either way, I will put the male back in a couple of days....and they continue right back with their courting/breeding activities.
Enjoy your books, consider all aspects, and do what you feel most comfortable with.
