Hi Nestnerd.
You're wise to join a forum to learn before getting your first flock. Chris is a font of useful knowledge. I'd also strongly recommend a search through the older posts on here as most of your questions will have been asked & answered a fair few times before.
I started using the forum in 2012 or 2013 & there's lots of helpful advice from back then on building runs, making them rat-proof, how much space you need per bird, why just having a coop without a run is a terrible idea, etc. etc.
One of my favourites is a thread along the lines of "is this poo normal??" with lots of pictures. (Spoiler alert: unless it's vivid green then it's probably fine!)
