FYI -Anne Arundel county recently changed their requirement to have livestock to needing a minimum of 40,000 sq ft. I was told last May, you could have 1 hen per 1250 sq ft. Here is an article from the MD Gazette:
Family loses case over pet chickens
BROOKLYN PARK - A Roland Terrace family's flock of pet hens must go, a county administrative hearing officer has ruled.
Stephen LeGendre denied a variance requested by Sandy and Andrew Kobus, which would have allowed them to keep their pets despite a county law passed this year that prohibits livestock on land smaller than 40,000 square feet.
The couple bought the hens for their children several years ago for Easter, They plan to appeal the Aug. 12 decision to the Board of Appeals.
When they applied for the variance, the family had five of the birds living behind the house. One has died of old age, Mrs. Kobus said Monday.
"Now it's become a real commitment to keeping them," she said of appealing the board's decision. "If we didn't, I wouldn't feel like I was doing everything I could."
Applying for a variance cost the Kobuses $180, and an appeal will cost them $280. About 40 neighbors have signed a petition promising to chip in money so the family can appeal the ruling.
