I was like you at first too. I started with 4 pullets which has been very manageable for me and I'm glad I started small because it is overwhelming. I picked mine up from a hatchery a couple hours drive from me. They stayed in a brooder in my garage until they were 8 weeks old. This was in November, they had a great deal of feathering and the weather was still somewhat mild (I live in NW Ohio). I put them in a coop (prefabbed that I ordered on line) and added a heat lamp but only turned it on if it got too cold (20s). I now know that probably wasn't necessary but I was a new chicken mom and worried since they were still so young. Funny, I got my coop in July and didn't get my pullets until September! LOL That was totally not necessary. In hind sight,I wished I would have had a coop design in mind and built. I don't know that you need the coop when you first get them but know that they may need to go in it by 6 weeks or so if you don't have a good place to put a brooder. WIth only 4, your accommodations don't need to be quite so large. My brooder was a large wired dog crate with the removable plastic floor, supplied with 1 foot high card board around the inside to protect them, some newspaper and pine shavings, a small feeder and waterer and a heat lamp. When they reached about 3-4 weeks, I made a larger brooder with card board boxes taped together, 3 ft. by 5 ft. with a piece of garden fencing over the top (they learned quick how to fly out). The floor was the same, newspaper and shavings feeder and waterer. It was challenging to clean but a lot of times I just let them out to run around the garage while I cleaned, they never went far. Once they were 6 weeks, I put them in their fenced run and coop area during the day but returned them to their warm garage at night until they were 8 weeks and then they were in the coop for good and used to it due to the playtime they got previously. So, that's my experience and I just learned as I went and continue to learn through this great web site. Good luck to you in whatever you decide.
