My friend had wyandottes that kind of looked like that, maybe a wyandotte? Sometimes feed store chicks get mixed up. what kind of comb does it have?
Another mystery feed store chick - Page 2
Looks like a dark Brahma. She's not laced, she's penciled. Lacing has black edging around the feather. Penciling is the base color edging the feather. And that's a pea comb. And since it doesn't have any solid black feathers on the chest, it looks like a pullet.
