Most of these are Gentoos but a couple of them look a bit like Chinstraps maybe. I don't know if they are ever found in mixed groups?

Yes, this is one of the mixed colonies. No need to report that. Just mark them as if they were the same species. More about in theFAQs: http://talk.penguinwatch.org/#/boards/BPZ0000006/discussions/DPZ0000adb
