Explain this behaviour...

I'm not a chicken owner, but this is weird behaviour for a rooster I found on Facebook videos. What is he doing to his hen? What exactly this behaviour called?

Those poor birds in the mud
Looks like he is trying to shelter her from the weather by using his wing.

Many years ago I saw this from a gander during a hail storm.
He is providing weather protection as best he can.

Under normal conditions one would assume that the male is trying to shelter the female from the rain. But in this case, I'm willing to bet it was a set-up meant to draw in more likes
