I am totally new to chickens. I go my first set of 6 chicks from a friend a little over 2 months ago. I made them a little run with dog panels and mesh so they could be out side while I was taking care of the horses and cleaning the barn. Well one got out under the panels. was lost for 3 days on the other side of the fence, I fianlly lured it back home and caught it. I do not want to ever have that happen again! Everyone is getting bigger and I just ordered my "coop" yesterday. I am wanting to build my real run this weekend. So, I want to be able to move the run, because I plan on putting in a few new sheds, and I want to able to move the run as the I do stuff to the property. So I am not wanting to bury wire underground for security. Can I actually put a layer of mesh on the ground attched to the bottem of the run?, like make a totally mesh enclosed box? (sorry if im not explaining well), and then put a layer of sand over it, so they are not walking on the mesh? would this work?
