I will *hopefully* be getting 5 - 5 month old Buff Orp pullets next weekend (if they are still available) and am curious about how long I need to keep them locked up in the coop to get them to return there at night. They will have a 30' x 15' run and the coop is 6' x 4'. Do I need to keep them in the coop for the whole 2 weeks if there is no where in the run for them to roost? I didn't know if that 2 week rule of thumb was mainly for free range chickens or not. I am worried about keeping them cooped up that long; worried they will get bored and start picking on each other and worried the coop might get too hot.
