Thank you for your reply, will you share the temp and humidity levels the you use? Also do you clean the eggs before going in the bator?I find that hatching turkey eggs is no different than hatching chicken eggs. The only difference is they take 28 days instead of 21days. I run the same temp and the same humidity for both.
After hatch they do fine with chicks in the brooder if you are hatching chicks with them. The chicks are called tutors they help the poults learn to eat and drink faster. If you don't have tutor chicks keep a close eye on the poults and make sure you actually see each of them eating and drinking dont just assume because one is they all are. Some poults are slower to learn the eating and drinking process and need encouragement. Though I personally haven't found that to be an issue with my poults. I like to add the flat shiny marbles(fish tank marbles) to the water and feed dishes to encourage them to peck.
As for free ranging with chickens that is fine. My turkeys LOVE my chickens and tend to like to hang out in the chicken yard. The one main issue that could occur if you have it in your area is blackhead being transmitted from chickens to turkeys. Chickens can carry it with no effect while turkeys that get it can become very ill or die. Also Turkeys can and will wander further than the chickens, mainly the hens, they like to explore. Also they will fly onto and roost on everything, your deck, tops of cars, roof of your house etc.
They also do not typically put themselves back to bed in their coop at night. If you don't herd then back before dark they will sleep where ever they please. Mine choose the railing on my front deck.
