I would love 12" completed blocks, so 12 1/2" with seam allowance. If you're up to sewing two blocks, I'll gladly do two blocks for you. I'd like the chickens to be fussy-cut and featured somehow. Everything else is up to you and your imagination.
You can go modern and fun like this wonky house block with a giant chicken that I made . . .
. . . or you can go with a traditional block like this one with chickens peeking out from each side.
