Burchell's or Chapman's zebra?

I think Burchell's but they keep both so it might be a hybrid. They don't have another paddock for their zebra, so they are mixed.

If I can only choose from these two I think it's a Chapman's, because its basic colour is full white and it has got stripes in its legs. But probably it's a hybrid as @amur leopard wrote.

The most recent London Zoo Animal Inventory lists two Chapman's zebra and two Burchell's zebra; no mention of any hybrids.

I agree with "HungarianBison". It look's like a Chapman's zebra to me; in particular, having the stripes on its legs going down to the hooves is typical of Chapman's not Burchell's.
