yikes! sounds like the need to move... but i'm going with the first response which is - they'll move when they are unhappy...
but
do you think they are sick?
do they have a dry shaded spot to lay with fluffy straw?
my sanaan is hiding in the furthest spot back in their barn ...out of the sun and today is a scorcher.... i put her feed and water back there so she doenst have a reason to get up.
My sis just gave us a gazebo thingy w/ mosquito netting, that goes over our patio table. So, the goats now have an umbrella, w/ weighted stand (goes outside the pen). It does have to be moved quite a bit, so this is probably just a temporary thing.
