My wife and I are totally new to chickens. We have a straight run of 12 australorp chicks and hope to end up with 5-7 hens. While they're in the brooder, we have been building a run for them outside. We live in the Philippines, so the coldest night of the year is around 65 degrees. The run we are building for them is 96 square feet and has hardware cloth on the entire bottom which we covered with dirt and we will add rice hull bedding on top. All of the walls also have hardware cloth. The predators here are monitor lizards, rats, and snakes. The run also has a roof and I plan to cover the back wall (where their roosting perch will be) and half of the side wall during the rainy season so angled rain won't get to the chickens. Also, the run is right against our house so they will be shielded from any typhoon winds we get (though if it's a really bad typhoon we may just bring them inside the house). My plan is to just build them a roosting perch with 2x2s elevated off the ground and to put in a couple of nesting boxes. Do you guys think that's enough or do I really need a coop? I'm thinking my run will protect them from the elements and predators and there is no cold weather to contend with, so it doesn't seem necessary.
