I work at the Rotary Nature Center within the Parks and Recreation department in Oakland, CA. We're right on America's first wildlife refuge at Lake Merritt and someone dumped a chicken by the lake earlier this week that we picked up to get rehomed.
We believe it may be a Rhode Island Red rooster - pretty sure it was crowing! But, since it looks fairly inbetween when looking at Rhody photos of both male and female online of similar size/age, we'd love to make sure. We don't know how old it is, so if someone can figure that out that'd be great! It's pretty friendly and doesn't mind being pet too much.
We think the previous owner trimmed down the tail feathers, as they seem to have been disturbed.
These were photos from my cellphone and I could take better ones tomorrow, if you need. Just don't have my camera on me.
We'd love confirmation on breed, gender and approx. age - it'll be easier to get it rehomed if we know as much as we possibly can.
