I know there are a lot of related threads but I'm hoping for some advice. I have 6 chickens who are about 14 weeks old and 2 just started laying in the last week. However, they all lay on the floor of the coop instead of roosting on the bars basically on top of each other. My concern is some lay in the nests. I am going to block the nests at night at least but should they start roosting soon? Am I being impatient? I had another group of 8 chickens previously who all figured out how to roost with the same setup and no help from me.
