Looks like it's coming along great! Just a few suggestions. Is that plastic poultry netting? If so, I would suggest that, before you're too far along and, especially if you have an issue with predators, that you look into replacing it with 1/2" hardware wire. What are your plans for ventilation? There are a number of excellent articles/discussions with respect to ventilation on this site. Be sure to post the final build.
It is the plastic type - that's all they had at the time. I live in a subdivision though. Other than an occasional cat we don't have many predators. I'm on the look out for the hardware kind though. Just temporary for the time being. On the top part. I have a door on one side with the chicken mesh and gonna do a window on the side. Will that be enough ventilation?
