I recently found out my 4 mo. old bantam Delaware pullet is a cockerel! She went from Della to Dell in less than 3 minutes! Now, I have been advised to use feed made of white corn to preserve his brilliant white plumage and white flesh. We live in NW Iowa, right in yellow corn country, and I simply do not know where to start. Can anyone supply me with some ideas? Names? Thanks for your time.
