Silver Laced Wyandotte cross hen?

[HamsHen50]

I have a year old SLW hen, and she was sold to me as a pure SLW. But she looks to be a mix, she has really bad lacing and has a much bigger comb and wattle. What breed do you think she is crossed with? Also have a look at her tail… it’s different to my other wyandottes.
