Fred,
I bred hard to breed dogs , Mastiffs, for years. I always found that the key to a good breeding male was to put him inwith some old hussies. I've used this theory in poultry for years,and it works. Put a cockerel yoy are planning to use in with some old hens. They will teach him manners,and you will get many more fertile eggs.
thedragonlady,
You got that right. That is exactly where the crown prince is right now.
