Hi Frank,Think of it this way 2 to 3 times more room for each Turkey as you would have for a chicken.
Roost space nesting box or run.
That would be a good rule of thumb and also the feed needed that would be close to whats needed.
This also depends on the breed as far as food consumption I here the Double breasted can really put some food away.
Raising chickens and Turkeys together check you area for black head state agri Dept, might have that Information.
If you raise Poults and Chicks together no adults and your area is clear of black head then there is almost no way to contract it.
If your area is clear there is a slim chance that the adult Chickens could give the Poults Black Head depending were you got them as adults.
If you raised the Chickens from Chicks and your area is clear of black head the you would be safe to raise Poults.
Feed the Poults Game feed starter till 10 weeks don't let them even touch the ground till 10 weeks also dry and then you can ween them off the starter then put them on Chicken Laying pellets and free range if possible from here there is a lot more learning to be done I'm still learning.
You heard right, BB turkeys will eat themselves to death, just like BB Cornish rock broiler chickens. They can not be fed all they will consume like normal chickens. They are both hybrids ad can not mate naturally either. They have to be AI. I found this out the hard way. Raised 15 to over a year old to find out their eggs were not fertile and I am not into AI. They became BIG turkeys though. The last 2 I harvested weighted over 80 pounds each on foot and I needed a tractor to lift them. When they were bleeding out and started flapping their wings, I got almost knocked out. I now raise only the white Holland breed that was the breed, BB Whites were bred from. Holland Whites are only a couple pounds smaller than the standard bronze, but much easier to pluck(no dark pin feathers) and taste wonderful. You are very knowledgeable. Thanks for all the good info I have read from you!!
