Hi, welcome to turkeys. You'll have to be careful, as some people fell they're even more fun than chickens! That's going to be a beautiful mix, with the possibility of several patterns. We'll want to see pictures. Even though you've probably hatched lots of chicks, turkey's are just a little different. Here's a link to a great article on hatching turkeys:

If you haven't already done so, you might want to check with your county extension office to see if there is a disease called Blackhead where you live. Chickens carry it harmlessly, but if they give it to turkeys the turkeys die from it. So there are some areas in the country where you need to take special precautions to keep the two species on the same farm, some areas where you just can't have both successfully, and other areas where it's not at all a concern.
When the poults hatch, you may notice that they aren't as precocious as chicks. While chicks seem to be born knowing how to eat, drink, scratch, dustbathe, socialize, etc, poults aren't quite so well equipped. So they need to be shown where their water and food are, and may need to have their beaks dipped. Keeping marbles in the water/food bowls can help, as long as the marbles are shiny and too big to swallow. Keeping a few newly hatched chicks with newly hatched poults can make life much easier, as the chicks act as tutors and teach the poults everything they need to know. (assuming, of course, that there's no concern about Blackhead).
Have fun with your poults. Be warned, though, when they get a little bigger, they fly quite well.
I was hoping to free range them. Do turkeys do well as free range birds?
