ok so the brown one is my 8 week old pullet and i know that she is a mix but i was wondering of anybody knew what she might be a mix of. i'm not sure what color egg she hatched out of but i know that it wasn't white
Its nearly impossible to tell for sure sorry. Best guesses can be made at full adult age. Crosses can produce endless outcomes even from the same pair of birds. And they can change color and pattern in the first couple of molts as well. Best chance would be to post 7-8 month old pictures.
