I have 4 week old chickens. The last few days we have let them out into the outdoor run for the day the weather has been so nice. It is connected to their coop. At around 6 PM I am crawling on my hands and knees as I try and usher them back into the coop for the night. ( not fun) I know adult chickens will make their way back in at dusk....will 4 weeks old chicks be intuitive to do the same? Thanks.
