Ok, its my second night as a chicken keeper. Its pouring with rain and very dusky. My wretched chickens are walking in and out of the coop and then back into the run, taking turns to perch and then come out again. At some point I need to shut them in for the night. Last night we put them to bed, I was hoping they'd go by themselves tonight as DH is out. At what point do I need to don my cagoule and go chasing them into bed?
