Hi! I'm a newbie and have learned so much from this site. Thank you! My chicks are now 4 weeks old and I'm now frantically trying to put the finishing touches on my coop and run. I'm building a run off of my chicken coop. The whole thing is in the middle of an old established rose garden in my backyard. The run will be 12 feet long and 4 feet wide. The sides and top are covered with galvanized wire in 1"x2" rectangles. The roses line both sides on the outside (those thorns are a bear!! ). My obstacles: How can I make this predator proof? Digging a trench around the run and burying wire is proving to be difficult because the rose bushes are so close to the outside edge. Is it possible to dig the trench on the inside? If so, how deep and should it flange in or out (and for how long?) What material is used for this? It seems hardware cloth is inflexible and hard to work with. Alternatively, can I lay hardware cloth on the floor and then bury it in dirt and sand? If so, how deep should the dirt be over the hardware cloth so the chickens don't hurt their feet? Thanks everyone for your help!
