You're right Larry - whilst the goats are wild in that they are left to their own devices and live outdoors all year they are rounded up once a year and tagged and given a health check. There was a big controversy last year as numbers had grown so high they were 'helping themselves' to local gardens - for a while there was talk of a cull but in the end around 30 were moved to a nature reserve in Surrey where they were needed to control the growing vegetation.
As for the smell the Billy Goats were fighting a lot (see my next picture) - does this mean their mating season was about to start?
