Mary:
I don't have a clue about ground turkey, but my guess would be that 7
hours is long enough for a ground meat. I tried the ground beef
mentioned on this list some time ago and it was horrible! I gave it to
the crows. Maybe I dried it too long also. If he is going to eat it
pretty fast can you refrigerate it to be a little safer? I guess it
might get kind of yucky when the oil or suet gets cold, though. If it
was me I would go ahead and give it a try.
Best Wishes to you and yours,
Love,
Bev
