Look for All Flock or Flock Raiser. I am sure the feed available to you is not the same as what is available to me. Here Flock Raiser is Purina's version of an all flock feed. I use an All Flock feed. It isn't the top quality but it was on sale today for $13 for 50 lbs.
I highly recommend a turkey saddle for her. If she goes broody, you need to either separate him from her or make it so she has access to her nest but in a way that he can't get access to her nest.
It is my experience that toms that are poor breeders do not get better at it with age. They are also the ones that unintentionally kill their hens.
