I don't know if you have the right parents for it, but she looks to me like a Dark Cornish x Rhode Island Red. A hatchery based RIR x Easter Egger would not support such dark color.
Malays have been the sweetest breed of chicken I have ever owned! But dark cornish is a possibilty as well altho they generally don't have those long legs. Either of those gamefowl breeds are great. Nothing is sweeter then a game chicken, even if they resemble a raptor at times.
