Has anyone used the EZ Spike or something similar to construct vertical uprights for a chicken coop entrance. From someone who has used concrete before to build a fence and then hacked for three days afterwards, I am looking for a simple alternative. This things allows you to hammer in a spike that holds a 4x4. The store said they are weak but I am just constructing a chicken run. Plus I don't want anything permanent. http://www.homedepot.com/buy/buildi...work/simpson-strong-tie-e-z-spike-122488.html
