My 9 chicks were getting a little crowded in their one rubber tub brooder so I moved 4 of them to a 2nd tub right next to the 1st - they share a heat lamp. The 5 who stayed settled down pretty quickly but the 4 who were moved were pretty panicked for a while trying to get back to their old haunts. It may not have helped that I wanted to try sand instead of pine shavings for bedding and the ones who got moved were in a very different environment. They eventually seemed to settle down and began scratching and investigating the new area.
