sounds like a possible cross to me. When you said spots, I immediately thought Cali Whites, but they have them on their legs too, if I am not mistaken. I think you may have a 'wait and see' chick. I got a cross last year that I guess probably 10 different breeds before she finally grew up and was obviously a cross with some kind of rosecomb. I love her and she is one of my favorite birds out here and I wish I knew what cross she is so I could have more.
Good luck. All will become apparent in time.
