As the name implies, we are "NewAtThis". I have built my own coop using a 10' x 10' existing space under our treehouse. I used YouTube videos and this forum to help me design it. We have a dog that would easily tear right through the standard chicken wire. So, I went with a 16-gauge 2" x 3" wire. The chicks are only 3 weeks old and can walk right through the wire at this point. We are keeping them in the hen house/brood for now. Can I just wait it out until they grow large enough to not fit through the wire or should[/IMG] I wrap the coop in a hardware cloth?
