Not a wink of sleep last night!!! I put my girls (5 weeks old) and my rooster (4 weeks) out for their first night and they did great!!! One thing though... they can seem to figure out how to get to the bottom part of my coop (it is an A fram and they enclosed part is on top with a ramp down). I put little bits of food going down the ramp, my boyfriend and I lead them up the ramp but I hope that they learn how to go up and down????
