Pour avoir de la moulée, les coop agricoles sont les meilleurs places. Le nombre d'appelants mâles vs femelles, à peu près moitié-moitié. Dépendamment du secteur, une ou deux douzaines peuvent suffir.
Do you speak English ? If so, you can ask your questions in English. I am sure there will be people pleased to see that this site hosts some English speaking persons ! Also, I believe that you would get the answers you're looking for. If you manage to write half in French (showing an effort like you just did with this subject), many will surely try to do the same in English ! For any missunderstanding, feel free to ask me for translation.
