My chickens have a large run but I like to let them free range in my yard . I have a terraced yard where the chickens have a lot of places to roam, however they have learned to come up to my top patio and deck into the open patio doors where the dog food bowl is. My dog stares at them while they peck at her food but does nothing. The problem is they make a mess of my patio, deck and sometimes my house. is there a way to keep them out of an area without installing tall fences.
