I had mounted the kill cone to the opposite tree on the far side of the yard. I used a portable dog kennel built for for a small dog to capture the cockerels. I put the cage down in front of them, with the door open, and baited the inside with kernels of fresh corn. The bolder hens would go in first, then one by one the cockerels would go into the cage, and I would swing the door shut and they were caught. I did this one at a time, and only the 5th rooster refused to go into the cage--so he was the one I still have. Carrying the cage to the kill cone, I would open the cage, extract the bird, who would be squawking loudly, and put it upside down into the cone, which immediately silenced it. When its head dropped out of the bottom of the cone, I did a fast and very final thoracic dislocation with a Fat Max Bypass Lopper. The birds did not taste good to the wife and I (a strong gamy flavor), but our dogs loved the taste. I did 4 birds this way and now I am down to 1 rooster (I haven't seen it mount any of the hens but he crows every morning-does that make him a rooster?).
