The well-fed black hen has taken up residence behind the electronic billboard at Glendale Community College for at least two months.
The chicken has dodged animal control officers several times by attempting risky flight maneuvers into traffic at Verdugo Road and Mountain Street.
The brazen bird was walking into the intersection, forcing cars to swerve around it.
Startled by traffic, the chicken quickly turned around and went back to the sidewalk.
Ricky Whitman, spokeswoman for the Pasadena Humane Society, which provides animal control services in Glendale, says the chicken is creating dangerous traffic conditions for drivers.
Whitman said the animal control shelter has received a bunch of calls from people concerned about the bird.
Animal control officials say without the extra food, the bird would become weak enough for them to catch it.
They say tranquilizers are out of the question because the chicken is so small.
Once the bird is captured, officials hope to find it a new home on a farm.
