In their natural habitat, alpacas have no shelter from the sun
or rain. Temperatures drop below freezing 300 nights of the year
in the puna. Therefore, alpacas only need shelter where the conditions
are markedly different from those of the puna. Having said that,
the unit value of stock in North America is much greater, so
more care needs to taken with these valuable animals than is
warranted or possible in the puna where infant mortality is higher
than in North America.
So, your shelter needs will be determined by where you live
and what you are trying to protect your alpacas from (whether
it be sun, wind, rain, snow or extreme cold) and also whether
you are using an existing structure or have the opportunity to
build a purpose built facility. Effective alpaca housing comes
in many forms to suit the needs and budgets of just about everyone.
