Maryland Indigenous Chickens ?
Chickens are indigenous to Asia. Originally they were scrawny birds, primarily valued for the cock-fighting and colorful feathers. Eventually, people turned to them for food and started hybridizing them into the meaty, heavy egg-laying creatures usually raised today.
We know of no American birds raised for meat or eggs. We'd recommend some online research or contacting the Native American Museum in D.C.
The Home and Garden Information Center does not focus on animal husbandry. For info on raising chickens, see your local county UMD Extension office http://agnrfacultystaff.umd.edu/node/1817
