     1        better than elsewhere?
              A.  No, it was not my purpose or my remit to review all
     2        the farms at Sun Valley.
 
     3   Q.   No.
              A.  That would be a very time consuming and tedious
     4        exercise, as you appreciate.  It is to see whether what
              I was shown met what I considered within normal commercial
     5        practice to be acceptable.  So, I only did one flock in
              this particular instance.  That was all I was able to do.
     6        However, having heard the reasons for why that one flock
              had such a low prevalence of severe leg weakness  ---
     7
         Q.   That is four and five?
     8        A.  -- four and five, that is a general policy,
              presumably, applied to all other flocks.  There is no way
     9        of discriminating between flocks on that basis, in which
              case it is not unreasonable to suppose that there were low
    10        levels of fours and fives elsewhere.
 
    11   MR. MORRIS:  Just a couple more questions on rearing, then we
              will move on.  Just on the subject of the lighting, just
    12        to clarify:  If I put to you that the lighting was dim at,
              whatever it was, 75 lux or 80 lux -- I cannot remember the
    13        figures you said -- would that be reasonable?
              A.  I would disagree.  I would disagree with that comment.
    14
         Q.   So how would you describe it in human terms, if I went
    15        into a room at 80 lux?
              A.  It is certainly sufficient to read a newspaper by.
    16
         Q.   What is daylight in lux terms?
    17
         MR. JUSTICE BELL:  That must vary enormously.
    18        A.  We discussed this yesterday.  Do you wish to proceed,
              go through that again?
    19
         MR. MORRIS:  Just briefly, yes, please.
    20
         MR. JUSTICE BELL:  You said it was about 100 out in the
    21        corridor, you thought.  Did you say that?
              A.  Just a moment.  Let me recap on my memory.  It would
    22        be between 100 and 200, I would suspect, because it is not
              a very well lit corridor.
    23
         Q.   What do you think it is where you stand there?
    24        A.  Where I stand now, I should think, holding up like
              that, it would be about 500, about.
    25
         MR. MORRIS:  I am not sure if that get us any further forward. 
    26 
         MR. JUSTICE BELL:  No.  Anyway, you think that someone with 
    27        average eyesight could read a newspaper in 80 lux?
              A.  Absolutely.
    28
         Q.   Without pulling it up?
    29        A.  With undue effort, yes, I agree.
 
    30   MR. MORRIS:  Does that not so low level of lighting have
              management benefits in terms of managing the herd, the
