What is a chicken roost?

Could you please clarify what you mean by "chicken roost"? Are you referring to a specific structure or place where chickens are kept at night for roosting, or is there another meaning to this term that I'm not aware of? In the context of animal husbandry, a chicken roost is typically a raised platform or perch where chickens can sleep and rest off the ground, providing them with a sense of security and warmth. Is there a particular aspect of chicken roosts that you'd like me to elaborate on?
