Issue with complex

[JRecoq]

Greetings,
I have peculiar situation on my side with FamAgg.

The Pedigree I use is quite convoluted as it come from breeding company data.

If I use a "complete" pedigree, several birds are duplicated accross families giving me the following message when using FAData :

Erreur dans kinship2::pedigree(...) :
Duplicate subject id: 125Duplicate subject id: 125Duplicate subject id: 125Duplicate subject id: 125Duplicate subject id: 125Duplicate subject id: 125

If I use a trimmed pedigree, the following error is given :
Generating the kinship matrix...Erreur dans kinship2::pedigree(famid = ped[, "family"], id = ped[, "id"], :
Value of 'momid' not found in the id list 4/3927518502234 5/3927518502234 10/3927518502234 11/3961511284313 4/3971527126014

I understand that the functions are doing their jobs and that poultry husbandry is extremely different from human one.
But in case of human, I suppose that sometimes a pedigree can contain several times a father or a mother, so how can this situation be managed by kinship2 which is the base of FamAgg

Below an example of a poultry family.

Many thanks for your time.
