Before buying a stock truck or assembling a float, take a little time to plan.
Goats do not appreciate being contained and are master escape artists! Whichever method you use to contain them, make sure it is effective, strong, and safe for the goats.
Goats can jump high and climb anything (have you ever seen goats climb a tree?). The sides of your transportation should be taller than the goats you plan to transport, and not be easy for them to climb.
