I was cleaning my coop weekly. Scrapping all the Pooh and straw out and putting fresh straw down. Then I talked to the man I got my EE's from. He said cuz its getting close to winter, I shouldn't take the messy straw out. Just put fresh straw on top to build up a nice thick layer to help insulate for the winter. It sounded like a good idea. What do I know? Now my coop stinks really bad. Dah! My worry is, I took a roo back to this man. This time I went to his actual "farm". I did not like what I saw. There were animals every where. Pened up, a dozen here, 2 dozen over there. Big pens with dozens of animals in them and then smaller pens inside with a dozen or so animals inside those pens. Not a thread of grass left anywhere. It was sad. I only left the roo cuz he allowed them to run free. He went into a barn, we weren't allowed to enter and brought me a dirty pullet with twisted toes who couldn't hardly stand. I felt so bad for her! (She's doing great now. All shiny and runs around the yard with my other chickies) anyhow my question is.......how often SHOULD I be cleaning my coop. And is there truth to leaving the dirty straw for the winter to help insulate? I want to do what's best for my chickens. All advise is greatly appreciated! Thank you.
