Incredibly messy handwriting that is nearly impossible to read. Usually the only person who can read it is the person that wrote it. Sometimes not even they can read it after a while. The writing looks like the footprints and/or scratches chickens leave in the dirt hence the name.
chicken scratch is lousy unreadable handwriting except to the person who wrote it but also a curse word to idiots who dont know what chicken scratch means or dont have an understanding of what chicken scratch means
My writing.
1) Used as a description of poor writing when it resembles the marks left in sand by a gaggle of chickens.
2) the act of scratching a chicken..or using a chicken to scratch yourself
