Hello and Welcome To BYC! check out the BYC Learning Center for a lot of basic information https://www.backyardchickens.com/atype/1/Learning_Center Here is a nice article with basic start up costs, as other people said, it really depends on what you are able and willing to make yourself, especially so far as the coop goes since that is usually the big expense, and if you are a diy and can find/ recycle material https://www.backyardchickens.com/a/how-much-does-it-cost-to-raise-backyard-chickens Coop placement will depend on a lot of things, your yard/farm etc layout (prevailing winds/ sun/ shade etc whatever weather is a problem), what is legal in your area (most citys have a law that says how far away coops have to be from homes), your weather, if you are planning on running extension cords in the winter for water heaters or lights instead of hard-wiring the coop, chickens will drink from a stream but if you plan on free ranging so that they have to get water there you may have a lot of losses to predators. You might want to do up a plat of your area and post it on the Coop/Run design forum for suggestions. www.backyardchickens.com/f/9/coop-amp-run-design-construction-amp-maintenance
