I have one girl who lays a beautiful dark brown speckled egg. My options are barred rock, rir, white langshan, columbian wyandotte, dark cornish, or white crested polish. I'm leaning toward the rir. I also have some mutts that I got from my sister. She says it can't be one of those because none of the possible parents on her farm layed speckled eggs. I'm not good at genetics, is it possibly a recessive gene? Could it be one of the mutts?
