Hi there,
I just moved from Providence to Ohio, but I am fairly familiar with the urban farming scene in Providence. The West End Area, encompassing Westminster and Broadway Streets and including the Armory Farmers Market at Dexter Field.
To get in touch with people there, I would point you to Cluck! an urban farm store that has been battling with neighbors over opening up. The link below is their facebook page, they should be great people to get introduced to having chickens in the city.

Best of luck with the move!
