EndStep()

NB development must be called here because they hares may be still getting milk from Mum.
In EndStep, the home-range centre peg gravitates a little way towards the daily activity area for today.

ON_Dead()

void Hare_Young::ON_Dead ( void  )

This hare has been killed.

Housekeeping for removal of the object, lets Mum know if there is a Mum

Reimplemented from Hare_Infant.

OnFarmEvent()

bool Hare_Young::OnFarmEvent ( FarmToDo  event )

protectedvirtual

Response to farm actions.

Checks to see if any nasty farm event has caused the death of the infant.
Currently there is only one response to those events where death is possible. However, this may not always be the case so the code is structured as for the other ALMaSS animals (i.e. it could be a bit easier to overview if it were written differently).

Young foraging.

The amount of time spent on this is dependent upon age. They can take in food up to a proportion of their needs increasing with age. This gives us a little problem because we don't explicitly define their needs. We assume therefore that the milk supply is maximal and that the the time available is all day - but that the max solid food intake possible is defined by age, following the data from Hacklander - this gives no flexibility in the proportion of max food but will cause differential growth w.r.t. milk supply.
