i just picked up 4 more chickens and i'm trying to figure out what one of them may be. 3 i know for sure 1 bantam hamburg, 1 black star, 1 silkie i believe is a roo but no crowing yet, but looks like a roo, and the last one i believe is a black cochin? looks very much like a cochin bun looking tail and feathered feet, dread lock feathers, not sure its a roo, because the comb/wattles look very much like my bo hens, but it crows and makes other noises? any help would be great, i'll try to get some pics, except that i don't know how to post them. thanks jim
