I've been using the deep litter method this winter for my 14 chickens who are now 28 weeks old, so far I've loved it. I intend to clean everything out and sanitize in the next three weeks or so. But I don't really know when to do this during the day as they are all making use of the nest boxes at all hours. I gather it would maybe take about 2 hours plus some drying time. I can't really allow them in as the big doors would be open and I can't let mine free range due to predator issues. Questions: 1. is it a big deal for the girls not to be able to access the nest boxes? 2. do you provide an alternate nestbox in the run? Would they get that? Input from experienced folks would be appreciated.
