Those look great. Since you are willing to ship, I would start a buy sell trade thread to reach a larger set of buyers. From there if you want to grow even more there are lots off craft selling sites like etsy.
Something to consider would be the male chicken owners. Sure the hens are girls, but I'm thinking there must be a guy out there that would want a jean fabric or a sports team fabric or even just a sports themed fabric like basketballs and hoops or baseballs and bats.
My intention was to let people choose the type fabric they want. What I have in pictures is just what I have in my scrap box from other projects. If you want denim, sports theme or even CAMO, not a prob the fabric store isn't so far I can't make a drive there. Thank you for pointing that out though, I just forgot to mention it. : )
