Well, one of my bantam roos, Charlie - a Buff Brahma - HATES Blue Jays. Hates 'em. There's a family of 3 who have nested in the tree in the corner of my back yard as long as I've lived here (a whole 3 years now - the Mom & Dad jay were probably there long before I moved in).
I put 2 cups of cat food in a dish, outside, every evening for two of my cats who do not come inside the house. Up on some cat furniture I keep outside by the patio door to my guest room, on a large wooden cable spool. Then I give some quality loves to the kitties for a while.
Every afternoon, a blue jay lands on the lamp post at the edge of the patio and waits. Looks around. Checks for cats and/or dogs. Then flies to the cat feeding station to steal a single kitty kibble. It flies back to the lamp post, looks around, then flies off with it. Sometimes it lands in the pasture and eats the kibble, then comes back for another, and sometimes it flies off into the trees with its prize.
This is in the front of the house, not the back yard. Many of the chickens range freely in my front yard for most of the day. Charlie has decided it's his personal job to harass those jays. He stomps over to the base of the lamp post, neck feathers flared.
When the jay picks up its one bit of kibble, Charlie rushes the cat feeding station. The jay flies to a fence post and waits. Charlie makes it to the post, the jay flies into the pasture and lands on the ground. Charlie changes direction and charges him, ALL flared up and screaming. The jay flaps up into the air as Charlie gets closer, then lands about 20 feet away. Charlie changes direction.
This goes on for several minutes until the jay is tired of the game and flies away with the kibble or eats it and then flies back to the lamp post. Charlie rushes back to the lamp post. Round two ensues.
Charlie is the handsome golden-orange fella in this photo.
Here he is, on patrol in the front yard.
