The top one who I thought was a splash is silvery. sadly she has clean legs. All my others have feathered legs. I am not breeding so I am not worried. I have another blue that is 10 days old and a black that is 10 days old. The Blue is lighter in color than this one. and the black is very black. ( the parents are Blue Copper ) These kido's are for my egg production coop and there will be no Rooster in with them. SO I hope none of these little ones are roosters.I had a black, blue and splash hatch eight weeks ago. The top one looks just like my splash one did, almost silvery on top. I see wing feathering already, and they are definitely not blue. The lower one is a blue, though they can be lighter than that. It looks like your blue may be a dark one.
How feathered are the legs on your splash?
