I discovered that this pattern makes an adorable chick-sized mini chicken if you use a few scraps of standard 4-weight yarn, a 5 mm hook, and 8 mm safety eyes. This is the Simple Stardew Valley Chicken free pattern, which can be found on Ravelry.
They are so quick and easy to make that you can whip up a whole tiny flock in just an evening. I made all three of these in just a few hours.
Each chick measures about 3.5 inches long by about 2.5 inches tall (not including the comb). The kawaii safety eyes came from this kit on Amazon. You can view more info about the yarns I used for these on my Ravelry project page.
The pattern was originally designed to be made with chenille blanket yarn, which produces a much larger softie (example photo from the pattern below).
