We ALWAYS and intentionally hatch chicks with turkeys and leave them together (though all of the eggs come from the our two farms so diseases are not a concern) the chicks save us the trouble of teaching the poults what to eat. There are a few diseased that can be carried over through an egg... but typically the disease will be picked up in the birds environment. The dreaded disease of concern is blackhead, familiarize yourself with it and talk to people in your area to find out their experience with it (these people won't have any turkeys but they had some once) We make sure that we accommodate the turkeys in every aspect of the incubating hatching brooding etc the chicks always flourish. If the eggs are coming from two different locations, and they are not certified, I would observe the flock from which the eggs came from and discuss the health history of the birds. Best situation is that all of your eggs come from the same repitable source that fancies the breeds and culls accordingly one who is actually a breeder and prides themselves in it, also identify the pourpose of the source of your eggs, if the pourpose is simply to make and sell eggs, you will simply get eggs (think hatchery style), if the source is a breeder, you will get a breed (of course if all you want is eggs...)... Once again, I cannot stress enough about knowing the source of your eggs.
