Where can I find the pattern for knitting the coats for ex-battery chickens?

I knitted one of the ones on here, i casted on 35 stitches and knitted for a bit (!) i measured against a frozen chicken believe it or not LOL, then i changed to a smaller needle (i started on size 3 big needles so it grew quicker!) then knitted in knit one pearl one rib for about 10 rows, you need 2 of course, i stitched three corners together and the top left one i sewed on a large button and made a loop from blanket stitch, so it can be put on the chicken easier, does that make sense? If you type in chicken coat in Google i think there is a pattern on the net.
