What are pop-holes?

Answer 1

Hen houses have two types of doors: larger doors for human use, and smaller doors (pop-holes) for fowl use.

Answer 2

Pop-holes are small openings or doors in a chicken coop or building that allow chickens to move freely in and out. They are typically used to provide access to outdoor areas for the chickens to roam and forage. The pop-holes are often designed with ramps or steps to make it easier for the chickens to enter and exit.
