"The only animals we didn't work with were sheep at the time - we have worked with sheep now."  The star went into detail about why lambs didn't make an appearance in the

first season of the show by saying: "Because we filmed the first series in autumn so there weren't any lambs." When Samuel asked the team why they didn't train with

sheep despite learning how to approach horses and cows, he was told it was down to the cost.  He explained: "I said, 'If one [sheep] went wrong do they just kill it?' And I

was told, yes, pretty much.
