Ask for advice, what kind of sheep is this?

(agricultural get Rich Network) ask for advice, what kind of sheep is this? -

I can't see the back. From the side, it looks like

Height, legs, head, back, horns, ears, hair, should be small tail Han sheep, but black hooves, long tail are rare.

There are two dark sheep in the back.

Personally, I think; 1. It is a group of small-tailed Han sheep with atavism.

two。 A generation of ewes crossed between small-tailed Han sheep and Suffolk, and backcrossed with Han sheep.

I don't know whether it is right or not, please give me a clear warning.

-- send more pictures.
