We got a new baby chicks in April and have a coop ready for them. We had old chickens that lived in the coop but they passed a while ago. I want to sanitize their coop because some our our older chickens got sick. I do not want any of the new ones to get sick. How do i thoroughly clean the coop? I has nesting boxes, a tree, and food and water dishes. Any tips on how to keep it clean? need advice quickly because i have to finish cleaning it tomorrow.
