I have noticed that my girls have been in the nest boxes. I have been checking them daily and when I opened them yesterday one of them sitting in the box. I have also noticed some droppings in the boxes too. They are about 18 weeks old now, there combs and waddles are getting bright red. Is the fact that they are exploring the nest boxes any indication that they are about to start laying? or are they just curious about them. just curious. Thanks.
