I ordered 25 chicks from a hatchery. My plan is to raise them to 6 weeks when they are fully feathered, then sell a bunch of them (at cost) to folks in the area who want to start chickens but want to avoid the incubator hassle. How much space do I need for them? they are large breeds like RIR. I don't have a lot of outdoor space, but have room in my garage--will that work? weather is very mild here. How long will I need to keep them in the house where I can check them frequently? 2 weeks?
