Welcome!
I was really intimidated and did tons of research before I started! BYC has been a great resource over the last 3 years I have kept chickens.
If you have time and space to dedicate to chicks, I would say start with them. I got 7 chicks of mixed breed knowing that I would give 2 away (due to city regulations) if they all survived once they got to pullet age. It was fun, a little messy, and surprisingly noisy to start with day old chicks but not as scary or hard as I anticipated. It was great to watch them grow and develop personalities. The only issue was one turned out to be a roo and I had to get rid of him. Know that no matter the breed, no matter the love, no matter the environment, some chickens will die unexpectedly. Thankfully, you will always find wonderful new breeds that you will want to take home. I am hoping to add some new chickens to my flock this year, and due to time/space limitations, I will go with pullets for this round.
Whatever route you decide, I hope you have great experience and lots of fun!
