Hello and welcome to BYC. There is good information on this site about breeds that others have pointed you towards.
About 6 months prior to us starting with chickens, I ordered a catalog (it's free) from the Murray McMurray website just to learn about the various breeds since I was totally clueless and didn't know anyone with chickens nor did I have knowledge to this web site. It's a pretty extensive list of breeds with pictures and brief summaries that include temperament, expected adult size, if the bird prefers foraging or confinement, good for beginners, families, heat and cold tolerant, farm or city, etc. It helped me tremendously to identify the breeds of choice based on our circumstances. It's also a fun catalog just to browse through! This is NOT an endorsement for that hatchery. I have never purchased any chicks from them and cannot speak to that. It's simply another resource if you prefer a flip the page hands on reference.
