roosting position

[hansolo]

I have 3 8 week girls that just transitioned outside. I noticed that their roosting position is different every night. I meant we only have one roost for the three will switch positions on it. One will be closest to door tonight and furthest from the door tomorrow night.
Anybody see the same and an explanation for it?

They don't know which is the best spot until they've tried them all
