In planning stage. Had hen houses in past life but would like to build a small tractor house for 3-5 hens. I want them to be able to scratch & peck in the grass. Would that work if I put 1/2" hardware cloth on bottom of cage. I want to protect hens from neighbor's dog and wild varmints. Is the hardware cloth overkill for the bottom of the run? Would regular chicken wire be enough to protect them? Thanks!
