I do not have Midget Whites... have Royal Palms, but mine are housed with my chickens. The only problem I have had was when I let my female turkey hatch her own eggs out. I had to make a pen in the coop for her and the babies. I had trouble keeping chickens out of it and Momma in. We finally pulled the babies and put them in a brooder for a couple weeks. Then they went into our "chicken jail" which is in the coop. Everyone can see each other but can't get to one another. They stayed there for a few more weeks and then we let them out with everyone else. They do fine. In the evening at roosting time..everyone kinda of waits to see where the turkeys are going to roost..and then they settle in on the other half of the roost. I think as long as there is plenty of room for everyone and it's not crowded, it works.
