Silkies not going in the coop at night?!

[BrittsChicks]

My silkies won’t go in their coop at night...
I have different flocks of silkies in different areas with nice coops attached to their fenced in yards but they won’t go in their coops at night! I have to pick them up one by one every night and put them inside their coop! Has anyone else ever had this same problem with silkies? Any ideas how to get them to go inside at night?... Any ideas or input much appreciated.
