ok, so my first chicks are now almost 6 weeks old. Nice weather now on west coast. They play in the run all day, but wont go up into the coop at night. They walk up the ramp, but wont stay inside. I figure if the weather is nice and they are safe from predators its ok that they sleep under the coop at night? Will they figure it out or do i have to put them there everynight myself til they get it? thanks to anyone who knows.
