I have 5 pullets who are 14 weeks old (first time mama hen here). They have a partially covered but completely hardware-clothed run that’s 184 sq ft and access to under the 8x6 coop. I do need to put more things in the run for entertainment, but I’m finding that they spend almost all of their time hiding in the dark under the coop. It makes me kind of sad, because I feel like they’re not being active except for during supervised free range time. The coop and run are tucked into a wooded area that is shaded. Is this normal behavior for their age, or could there be something displeasing about the run? Also, they were pretty social up to around 10 weeks old, but I was out of town quite a bit in July and have noticed they are much less friendly now. Could this change be a teenager thing? Thanks everyone!
