My chickens are about 16 weeks old. I noticed one of them dust bathing on the coop floor which made me worry this habit might increase its chances of lice or mites. I am doing the deep litter method. I did have their dust bath bin in the coop but I moved it outside in the run because of needing more space in the coop for the nesting boxes plus I thought reducing the dust would be better as well. They have been using it in the run just fine so not sure why it was trying to do dust bath in the bedding in the coop. Should I be concerned? Should I move the dust bath back into the the indoor coop? If it keeps happening Should I stop using the deep litter method to prevent lice or mite issues? Thanks in advance!
