About

suite de la raterie du domaine de Victor et olaf , cet affixe ne convenait plus à la raterie. la sélection , l’âge des reproducteurs mâles , la manière d’assurer le suivi des différentes familles … ont beaucoup évolués en près de 3 ans. j’ai donc pris la décision de trouver un nouvel affixe afin de caractériser ce renouveau.
