Hi and welcome to BYC - glad that you have joined us. It seems like you have all your ducks in a row (no pun intended) with your coop / brooder builds which is great.
Your state thread is worth joining as you will get to know other BYC members in your area (https://www.backyardchickens.com/t/270925/find-your-states-thread). The members here are amazing - very friendly and helpful, so if you need an answer to a question or simply want some reassurance that what you are doing is ok, then post away - we all help each other out here at BYC.
