Welcome. I agree as well with @N F C and @DobieLoverHello and welcome to BYC!Glad you joined.
I agree with @N F C. Start with 3 chickens minimum and don't get a pre-fab coop. Modifying a shed or similar existing structure is so much easier than building from scratch. Make sure you visit the Coop and Run Forum before building so you fully understand what makes a proper home for chickens.
Good luck with your new adventure!
