How do you keep yours clean? We are on our second batch of chicks. Our other 5 girls stopped laying after 2 years so they went to a friends place but ANYWAY! Our last girls we had a hard time keeping their coop clean. They never roosted, they sat and looked out the bottom of their second floor (A frame coop with chicken wired bottom). The coop floor was just the ground we covered in landscape fabric and chicken wire. Should we maybe switch over to placing wood on the floor???
