Truce Proclamation

This question is probably asked before but i couldn't
find it with search.

When you use the pigeon for 12 hours of truce it has
to prepare for 12 hours first.
Can you for example use 3 pigeons at once so you will
have 36 truce hours, or will you have to wait for
the 12 hours preparing and use another pigeon right when
the first 12 hours of truce start to have another
12 right after the 1st period ends ? And so on with
eventually other ones.

I like to have say another 48 hours of truce to
set up a proper defence first.

you can put the dove on three times, but it will always only last twelve hours and then have a twelve hour prep in between. If you have a Lada then after the 12 hour prep you can have 36 hours of truce

Thanks for your reply, what is a Lada exactly and how can one get it ?
