I am new to chickens and purchased two chickens as chicks from a farm, they are now 6 mths old and hugh! I do not know what breed they are. About 3 mths ago I went out to my back yard and found 3 more chickens , no one in the neighbor hood will claim them. There are two solid brown chickens and one very small white chicken. They all lay eggs everyday. Can someone help me identify what kind of chickens these are.
