Soo cute but not wrong there are many breeds that have the chipmunk appearance. You have to know what breeds male and female were together sharing the same living space to guess. Many wind up with barnyard mixes.
I personally could not tell because an Old English Game Hen or a Golden Laced Wyandotte might both show a chipmunk appearance in their young baby chicks. Here is site that checks genetics though if interested. http://www.avianbiotech.com/
