horsefield twitching hind leg in walking

[Yxx]

I noticed the other day in walking our horsefield in the backyard that one of his hind legs (not sure which now) twitches several times before he successfully started walking. At that time I wondered if it could be caused by itching or the hot ground. Yesterday I shot him eating in the morning and captured similar twitching. In the film, his right hind leg first twitched then he lost balance to the right before successfully walking. Could someone take a look and share with me your view if this is normal or not? Thanks much!

I am not sure. I have not seen this in my Russians. Curious to see what others think.

I just noticed I didn't enable video embedding. I just turned it on.

Looks normal for the terrain he was mowing over...
