I may be mistaken however I thought you were asking for chicken patterns rather than chicken fabric. I found one that does not need to be PP'd or appliqued. See attachment.
I have PM'd an excel spreadsheet that shows how I would make the chicken. I have also included the link where you can buy a pattern. I rarely purchase patterns however I am always willing to give credit for where I see a pattern that I try to replicate. I also included a picture of the original quilt. My favorite chicken is the one that they made with black fabric with white polka dots.
