So my chickens have not been laying for 2 weeks now. I have been trying to find out why, asked them they wont tell me! I thought they were molting, there are some feathers on the floor, but only from 1 hen. We clean the coop 1x a week. We sprinkle wood ash on the floor and in the cracks. Then we use straw in the coop and in the plastic next boxes (the get washed each week too). Now we cleaned the chicken coop today and found mites under the roost (of course), and looked a bit better and found them EVERYWHERE in all the cracks above the roosts (none on the floor or next boxes)! I can not tell if there is anything "wrong" with the chickens, they look okay. 1)Do I need to power wash the house out with water? It's wood on the inside, some is painted some is not, and there is wood ash everywhere. 2)Can I spray the coop with Neem Oil (bought to kill bugs on organic fruit trees)? 3) I have DE and would use it but dont know how to get it on the ceiling Thanks for the help.
