3bratz, that looks like a hen to me.
And yes, there are turkey charts -- they originated in an awesome book I found at a used bookstore: Turkey Management by Marsden and Martin published in 1945 (when everyone had heritage turkeys). The info from the book has been republished in a new booklet published here:

I forget which chapter has the chart, might be chapter 13.
Good luck!
