I'm sorry to respond in English. I've only once came across a peregrine pair who succesfully raised 7 eyas.
Most of the time there are 3-4 eggs.
Incubating is the major problem with so many eggs. The broodpatch is not large enough to come in touch with all the eggs. They cannot be evenly warmed and so it is not effective, and so nature decides that 6 is the maximum.
And feeding such a bunch of hungry birds is a problem as well, especially when they turn into juvi's.
