tieing up or leaving loose in pen?

Should I tie up my calves or leave then loose during this summer when there under fans?

I would tie 'em up.  We have our calves tied up every day year round, typically 10 to 12 hours a day, less on the weekends.  Just constantly rinse them and put 'em in front of the fans and you should be good.

Agree with FJB

I meant that I agreed with RankeCattleCo

i would leave them loose-  especially with calves possessing structure that is questionable to begin with.  Even if the only exercise they get: is turning in a 16x16 circle, it is more than shifting from left to right. 

When you have a show string of livestock, who are on the road nearly all summer- not only do they tire out towards the end-- but any hidden, or slight structure problems really show about state fair time-- the worst to have that appear. 

When we were showing real hard-- we always stole gates at the grounds to set up pens to leave the calves in overnight outside, and we opened up alley ways to run the lambs back and forth.
