so glad you have joined us.
IMO you have already started out the best way - study, plan and get your flock in the Spring is the best way to go.
Decide on why you want your own flock (eggs and fun is #1) and how many/what breeds do best in your climate and what source to obtain them.
If you want layers - try to get them either as sexed chicks or elect pullets. Otherwise make plans for possible roos-rehoming can be difficult.
** I would start with the babies - those early days are so much fun and an adventure not to miss**
Decide where to place your coop/run, check out the coop/run forums to see what fits for you.
Pay attention to the space they need - build bigger than the minimum. It is hard to increase their home after they move in
Feel free to post questions in the forums, you'll find a lot of helpful, friendly folks around here.
You are beginning a great adventure, enjoy it all.
