Well, I put my eleven 6 week old chicks spent their first night outside. I had them in with my older hen and she's really become taken with them. Last night I put them to bed at dusk and the hen walked in then all the pullets followed her, closed them up and went inside for dinner. I checked on them at 10:30 and couldn't see them at first, small coop with open top. But I did hear them, so I took a stick and started prodding the nesting boxes that I couldn't see into. Found them all in one nesting box behind the feeder with the hen at the opening trying to cover them all with her wings. Tonight I'll take my camera and try to get a picture.
