Are they living together now? If I got all the boys done together ( do you mean the same day?) I would probably put them back together in the clean cage unless some seem more in pain. All my boys except one could be put back in as soon as they were home.
i recently had my boys neutered. same day. they did great together afterwards because they were both too loopy to mess with each other lol. a few days out and you couldn't tell they ever had surgery
