So, my chickens are almost 13 weeks old now and I'm starting to think about the nesting boxes. When they were smaller, I had the area blocked off so they wouldn't get in the habit of laying in there but now that the hardware cloth has been removed, I'm clueless as to what comes next. Our entire coop has sand in it. Is sand okay to use in the nesting boxes, or will I need to put something else on top of the sand? Now here's the bigger question - I've been looking at nest boxes and they all seem to have side walls for privacy. Mine don't have that. We had a local company build our coop and they basically constructed 2x4s to make up 8 connecting squares (picture below.) Will that be okay? It doesn't seem like they will have a lot of privacy.
