Police say a man angry with his tax situation left a flock of chickens inside the state revenue office.

Louis Adler, 66, was given a trespass notice on Wednesday requiring him to stay away from the Oregon Department of Revenue in Eugene or risk a citation after leaving 7 chickens in the lobby.

Police and an animal welfare officer rounded up the birds, which were taken to an animal shelter. No people or animals were injured.

State agency spokesman Derrick Gasperini says the staff had prior dealings with Adler, who was "frustrated by the outcome."
