THE BULL SYSTEM

Lock them in boxes, introduce cocks and they will mate up to the hens, as the cocks will probably already have claimed a box they should mate to the hen in their box. Leave the cocks overnight. Take a note of the boxes the hens are in at this point.
Remove cocks in the morning, let hens out of boxes for an hour for food and drink, introduce cocks again and leave until morning. Take a note of the mated pairs and box numbers.
