Just wanted to share our first coop! We have two five week olds out there right now. the plan is to add a tunnel from this coop around my garden and along the back wall to where I am planning on building another larger coop. I have two more girls still in the brooder. Any suggestions? The tunnel will be PVC pipe frame, covered in chicken wire overlaid with hardware cloth. With rebar woven along the bottom ends and buried under rock. I live in Las Vegas so my biggest predators are cats and other large birds, and my11 yr old toothless poodle.
