Please explain the purpose of placing these blocks in these locations in the photos.  Interested because have building in weaning pens that I need to protect and have been struggling on how to do it.  Guardrails attached to the barn, have been the best answer so far and really do not like that option, for various reasons.  Placing blocks might be answer.  Little worried about animals hitting them, when they act stupid.  Surprising what we see sometimes to use in operation.  Other photos shows blocks stacked with ends (small side). Doing that really allows more pressure to be put on the wall.  Never thought about using the small end.  Would take lots of blocks, but opens up various options.  Thanks for Sharing.
