Well, I have found a solution for my excess cockerels that I cannot sell. I intend to caponize them. During the first weekend on of March, I worked with a mentor to caponize nine marans cockerels. I own the "Chinese tools" which make the process easier. So the excess cockerels will grow out as fatter, heavier, laid back, non-crowing, tender capons for the table. If anyone is interested in learning to caponize there is an excellent thread on BYC and some great teachers/mentors for learning this old time art.

I have a friend who is going to teach me to caponize this summer. She had a class last month on it but I was unable to attend. Looking forward to it!
