「Fodder」that is「wrapped grass, or, emerging shaft of head and neck wrapped inside skin slit of feet (doubled)」refers to someone or something that is「still in the nest」and cannot leave it: a FLEDGLING (cannot fly away or escape a predator, no life experience, easily eaten, naive, and so on), a newly-hatched bird, baby CHICK. A DOLL, or a PLAYTHING (looks pretty, no brains, cannot struggle no matter what). Soft nesting was used as a cushion after the foot-dis-integrating procedure as a place to rest while the pain was still too intense for any other movement, resembling the type of nest used by a mother rabbit for her 'bunnies.' A SQUAB is young, newly hatched, or unfledged pigeon. Ducklings have webbed feet as did Chinese service providers and concubines.
　This glyph is associated with a doll festival held annually March 3, celebrating「underaged prepubescent girls」and interestingly,「chicks」and「dolls」are both names for young human females in English also, terms that were probably brought back home by upper-class English opium pushers living in China (or,「drug lords」).「Hayroll, fodder」is a consumable item (hay or grass eaten by large farm animals), an often inferior item or resource (treated as having little or no value), that is in demand (to be devoured, or, to be rolled in the hay) and usually in abundant supply (there were always 'too many' little girls since parents wanted boys in China. Girls were 'inferior, treated as having little or no value' except when sold as sex slaves)…that was the world back then, folks…maybe, still is.
　The doll festival nowadays in Japan is purported to celebrate healthy little girls. See 丹秀雛 and the Hina Matsuri, or little girl festival:「…the origin of this custom of Japanese Hinamatsuri, could be said that it dates all the way back to ancient China. In ancient China, it is told that there was a custom for people to go into the river, to purify themselves on the first snake day that comes at the beginning of lunar March (calendars corresponded to Oriental zodiac animals as well as several other things such as time, year and direction ). This custom is said to have derived from a Yao (an ethnic minority hill tribe originating in southern China) tribal custom, a festival of spring worship in southern and southwestern China. The Yao custom of this spring festival, is told to worship dead females along the riverside on the 3rd day of the 3rd month of the lunar year…」
　　[　https://www.bite-japan.com/kako/calendar03-e.html 2014-02-15, emphasis ours] but no mention is made of the cause of death, such as a gangrenous foot infection. Hinamatsuri in Japan is celebrated in various ways, two of which are drinking of thick, paste-like, sweet amazake, and eating Venus clams (hamaguri)…you guess why. Hinamatsuri is also referred to as 'Peach Flowering,' and while there are peach blossoms in early March in Japan, there is also some similarity between the shape and skin texture of peaches, very young girls, and blossom flowering/deflowering. The Japanese did not practice foot dis-integrating, generally, and merely copied the Chinese by adopting similar festivals without knowing the original purposes behind the traditions. Profuse bleeding after a botched foot-dis-integrating and cinnabar accounted for the traditional red carpeting used under the figurines.
