Ya know.. I figured that and am glad to have my thoughts updated. If kept in a cage with no exercise, I am SURE they would of course have legs unstable just like a human would! So cool... I will definitely have to think on that then. BUT the STANDARD CROSS you say? Ok. I will go research on them and see if they are available for me from some farmer around me... SUCH GOOD INFO!!!!I also did not have any of the horror stories that I have read about.
