Scientists have observed that if there are more hens than roosters in a henhouse something happens quite different than if there are more roosters than hens.The answer does not involve egg productivity, quarrelling, noise or eating habits. What happens?
A hen can change sex over time, that would only be in the situation whereby the hen numbers far outweighed the rooster numbers, as a general rule you have 1 rooster/cockerel per 8 hens I think
It is not sex change.I do not know the answer, but it has been clarified that it concerns their behaviour. This was the result of experiments by scientists.
