Hello and welcome to BYC, You found an Awesome poultry Forum to be a part of with many great knowledgeable members who are more then willing to jump in and help you with any questions you may have.
Welcome to BYC from another newbie! I, too, am in the process of planning a coop and on getting my first chick's this spring. Also from Washington. There is so much information on this site it is scary!
Would love to stay in touch to see how you progress during the upcoming year!
