From the article: "The results suggest that domestication has led to epigenetic changes. For more than 70 % of the genes, domesticated chickens retained a higher degree of methylation. Since methylation is a much faster process than random mutations, and may occur as a result of stress and other experiences, this may explain how variation within a species can increase so dramatically in just a short time."

Epigenetics, Epigenetics and more epigenetics.
For some time I have been claiming that epigenetic inheritance is a problem for evolution. Here we have Science Daily agreeing.This rapid ability to produce variation is in agreement with IDvolution.
