It started with a cluck.

Sarah Gessler, mid-speech, had let out a loud squawk that echoed around the crowded auditorium.

“W-wait, I meant to say-AWK! BUH-GAWK!” The attractive girl’s head jerked as she echoed her first cry with another; then another.

Her opponent, Mary Sahn, simply smiled. Up until now, she’d been on the verge of losing to Sarah, their debate utterly one-sided. But now none of that mattered. Sarah had contracted the Transformation Flu, and a particularly nasty strain at that.

Of course, Sarah realized it too-though she refused to admit it. Desperately, the girl prayed that it was some sort of mental break; that she wasn’t actually becoming a… No, she couldn’t even think of it.

A prickling settled along herself as she shuddered, countless pins and needles settling across her flesh. She looked down to her arms in a blind panic, watching as quills forced their way out from what was once smooth, supple skin.

She watched as they blossomed soft hairs, becoming long and white feathers. Desperately, she pawed at them with her hands, only to squawk in terror as her fingers merged into useless lumps. Her arms buckled and warped until they were oversized wings, wings which she flapped in terror.

“SomeGAWK! HelPUGAWK me!!!” She looked out to the crowd in a panic, stumbling from her podium and falling onto her misshapen hands.

“Oh, don’t worry. I’m sure you’ll be put in a nice farm.” Mary crooned from above her, a cruel smirk across her lips. “And to think you were so close to becoming student council president.”

Sarah worked her lips soundlessly, unable to come up with a response. Then her eyes bulged as her lips began to move of their own accord, stretching out from her face. Soft, pink skin became little more than hard golden enamel, the same as any common avian’s beak.

“NooOOAWRRRGK!” Tears streamed from her face as she fell to her knees. They clacked against the floor, and she looked down with a shuddering sob. She hadn’t even felt them become knobbled chicken legs-though now that she was seeing them change, she could feel her feet reshaping very vividly.

Heart pounding, Sarah watched as the canvas of her sneakers bulged; then split. Three avian clawed toes burst from her shoes, flexing as they tasted the air. The girl squawked out a scream as her new toes clenched; then another as a fourth toe exploded from the back of her feet.

Everything about her was being molded like clay, reshaped by a callous virus. Her hourglass figure ballooned out; neck stretched; head shrank. Everything human about herself was lost to an avian body, one clad in feathers rather than skin.

She worked her clumsy beak with another loud squawk, feathers literally ruffled as she realized the worst was yet to come.

It seemed that Mary saw this as well, and the girl chuckled darkly. She walked over to the human-sized chicken, hooking a finger through the straps of her exposed bra. “You know, you’re not done yet. You’ve got all these people looking at you, so you might as well give them the show that they’ve been waiting for.”

Sarah squawked in horror, flapping her arms hard as she was lifted slightly from her feet. Even at this size, her avian body was light enough for Mary to lift. Her heart pounded harder as she realized that her feet were rising from the ground faster than Mary was lifting her in turn.

She was shrinking, and that in turn meant that her brain wasn’t long for the world. Sarah had seen it happen to enough victims of the virus to know that she was already lost.

Even now she could feel herself slipping; feel years of her old self washing away. “AWWWRK! BUGAWK!” She kicked her legs and flapped her arms, shedding her clothing as she struggled to retain her mind.

She wasn’t an animal, she was a person! She egg wasn’t a chicken and wanted to lay eggs had to stay cluck like an animal

Thoughts that weren’t her own swarmed over her dwindling personality, crowding them and utterly dominating them. She choked out sob after squawking sob, her whole body shuddering. Then she jolted in horror, feeling something press against her ass.

It was enough to restore some semblance of thought to the girl, if only for a moment. Her eyes bulged and she whimpered with denial, only to croon a moment later as a large object crowned around her swollen avian cloaca.

She didn’t know when her ass and pussy had merged into the in human orifice, all she knew was that there was an egg sliding from it that had to be laid, and laid now. Instinctively, Sarah dropped into a low squat, screeching as the egg slipped from her to land on the ground with a dull thud.

The pain was enough to drive her thoughts from her head, and she squawked as she realized she couldn’t even remember her own name. She squawked in horror, desperately trying to remember…

She blinked, unable to even grasp the concept of remembering. The hen’s panic slipped from her mind, and she let out a quiet “pock-pock-pock”, waddling around the stage exactly like the dimwitted animal she’d become.

There was nothing left of the girl she’d been; nothing that remained of Sarah. In one fell swoop, the Transformation Flu had claimed the life of another girl, leaving her forever as a mindless animal.
