Actually, chicks will gravitate toward the highest perches not long after moving into the coop. Low chick perches are almost always shunned, much like kids shunning the kiddie table at Thanksgiving.
Bottom line is chicks generally do very well upon moving into their coop. In the beginning of keeping a flock, I had just one coop, and moving chicks in with adults can be exceedingly challenging because they are afraid of the adults, and the junior adults can get to picking on the little ones, making it even harder.
Now, I have a second coop partitioned in half where my two rooster live in one half, and new chicks have the dedicated other half. This makes moving into the coop a breeze since no adults are in there to bully them. When the chicks are around a year old, they almost always move into the main coop on their own volition, usually conveniently in time for me to move the most recent batch of chicks into the chick coop.
