Perfect.  Couldn't be easier to assemble or simpler for portability.  Light weight but made of durable material.  We've been using it to exercise our growing baby chicks and plan to use it for the baby goat that's coming soon.  It may end up being a more permanent pen in our barn.  All it would take is to secure the pen on two sides to the wall with brackets.  Perfect! Nearly instantaneous and I couldn't begin to build anything for that price!
