I was only going by info given.
In you're original post it says mom is a barred rock.
So idk if you're looking for genetic info you need to give full info about parents.
I don't think it is barring. I think its just uneven blue.
Barring is hard to see on young blue chicks but seems easier to me since working with lavender with barring. Now that's hard to see.
I think its not barred and a female.
