semi-trap nest box ??

[FiveMoreMiles]

I let my turkeys set on there own eggs.
this year i ended up with 5 hens going broody in one nest box.
to prevent this i would like to build a Semi-trap so that only one hen at a time can enter the nest boxes.
I cant find any information on semi-traps.
can any one help me understand how the traps work and how to build then

Unfortunately I don't know anything about these traps you talk of. But what about their own brooding pen. Now I don't have turkeys but my good friend does and has one broody to a pen and it worked very well for him. Had tons of babies last season. This is what I do for my broody hens. HTH
