My theory about four winged dinosaurs

So I was wandering around the site, when an interesting idea stroke my mind, a theory about four-wingered theropods, such as Microraptor and Sinornithosaurus.

But let's begin with the beginning.

I learned somewhere about a special breed of chickens, the Duccle Belgian chicken. What is there so interesting about this bird? Well, those chickens have feathers on their feet. And not fluffly fur-like feathers, but developed, strong feathers. Now, those birds walk very silly, raising their feet very up while stepping. So I thought this could happen in feathered-feet raptors too, when walking to the ground. Raising up their feet would prevent them stumbling because of the elongated foot feathers. The more I think about this, the more I think this theory is very likely to happen.

Here it is: a video of the chicken's walk:

So, what do you think?
