Cassanova 2 – Boy or Girl?

So after Cassanova 2 took over a year to develop into a cockeral or was a hen who had a sex change op, I thought I would check out which is possible.

Cassanova 2

And it turns out that female chickens can on rare occassions turn into cockerals.

“Female chickens have just one functional ovary, on their left side. Although two sex organs are present during the embryonic stages of all birds, once a chicken’s female genes kick in, it typically develops only the left ovary. The right gonad, which has yet to be defined as an ovary, testes, or both (called an ovotestis), typically remains dormant.” http://www.livescience.com

Certain illness can cause the left ovary to regress allowing the right sex organ to develop which can now due to male hormones turn into a male.

While Cassanova 2 doesn’t lay egg now, he will not become a father.

So I now have a rare cockeral.
