What is the source of the tradition that animals can speak on Christmas Eve?

If one Googles [animals talking on Christmas Eve](https://www.google.com/search?q=animals+talking+on+christmas+eve) a wide number of hits will mention this practice. I get the connection to the animals in the manager, but I'm trying to ascertain the origin of this Christmas legend. Who practiced it first and when? How widespread is it? And, at what time does it work?
