     2   Q.   That I can understand.  I think you mentioned it earlier,
     3        the use of the fans is a summertime expedient; is that
     4        right?
     5        A.  The fans are used all the year round and we would just
     6        use more fans in the summer time than in the winter.

     8   Q.   Is the building in which the chickens live temperature
     9        controlled?
    10        A.  The building is temperature controlled.  We have
    11        thermostats which govern the use of heat and the use of
    12        ventilation.
    13
    14   Q.   Whose responsibility is it to see that the correct level of
    15        temperature and ventilation is maintained through the year?
    16        A.  The stockmen, farm manager on the farm is responsible.
    17
    18   Q.   I take it they are trained in these tasks?

    21   Q.   One other thing on environment/index.html">litter, Dr. Pattison:  May the design of
    22        the drinking, whatever they are called, we can call them
    23        drinkers, I suppose, affect the wetness of the environment/index.html">litter?
    24        A.  The design is very important and the traditional form
    25        of bell drinker (which was very easily tipped or knocked
    26        and spilt water) is now being replaced by nipple and cup
    27        systems of drinking, where there is very much less water
    28        spillage on to the floor and this is highly desirable.
    29
    30   Q.   Do you at Sun Valley still have any bell drinkers?
    31        A.  We still have some bell drinkers.  These are being
    32        replaced over a period of time.
    33
    34   Q.   I mentioned water in relation to environment/index.html">litter.  We can take it as
    35        read that birds need to drink, yes?
    36        A.  Correct.
    37
    38   Q.   They need to drink, what, when they feel like it?
    39        A.  They drink whenever they feel like it.

    41   Q.   How does the system cope with the increase in size of the
    42        birds as they remain in the sheds?
    43        A.  The feeders and the drinkers are raised as the birds
    44        get bigger.
    45
    46   Q.   That is a uniform increase in height, is it?
    47        A.  They tend to be, it tends to be uniform.  We have
    48        mechanical winches which allow the more modern systems to
    49        be raised and lowered.
    50 
    51   Q.   How is that done?  Is that manual or automatic or how is it 
    52        done? 
    53        A.  It is all done manually but with the assistance of
    54        winches.
    55
    56   Q.   Imagine for a moment that you are a bird; at what level
    57        would you find your drinker?
    58        A.  The aim, the recommendation is to have the drinker at
    59        shoulder height.  So, in other words, the bottom of the
    60        neck of the bird is where we aim to have the drinker so
