Q

What is the biggest downside to herding behavior?

A

they will stay as a group no matter what, so if they feel threatened and you are pushing them too much, they could go through fences together or even escape from pens to get back to the rest of the group.

stress depletes energy stores in the muscle and makes the muscle dark, firm, and dry
