One of the things that chicken have issue most is when there environment is not clean. The environment must dirt free and cleaning from time to time helps the chicken to be free from having diseases such as fowl pox and this fowl pox can affect them at there head, eye, mouth and this can disfigured their face and apart from that it will prevent them from eating and when they are not eating they have detard growth which can even result to death.
For my birds i clean their every week or when i noticed that house is getting dirty i clean the dirty sawdust away and apply new one there.
For the cleaning i use broom , packer and bucket to pack the dirt.
