Spencer hung up the phone. His plan was flawless. Chad's bovine instincts will get him pumped up into a perfectly average dairy cow, and all he needed to do was wait. Three hundred pounds of feed in a day would be impossible for most cattle, but those nanobots would "help" Chad immediately bulk up for the next day or so.
In fact, wouldn't it be better to stop staring at Chad so he could really feel the difference in his size between now and then? The rest of his tasks were done, more or less. He could spend the day messing around with friends, take it easy for the night, and check on Chad the next morning. All it'd take is another pack or three, and he would have his dairy cow by tomorrow morning.
A crueler thought crossed his mind. He could only put one pack in, and let the nanobots finalize Chad as a particularly petite dairy cow. The thought of Chad getting bullied by the other cows, struggling to keep Ferdinand aloft as he was mated, and having to drag around an udder one size too large for the body, it all excited him. Sure, he might lose points with the 4H club, but he was already thinking of excuses of bad luck with genetics, or maybe claiming Chad was a charity case and his success was in spite of mistreatment by a previous owner.
Yes, he had to do it. "Chad, I can tell by that vacant look that you're not listening, but this is too hilarious." He tossed another split bag of feed into the enclosure. "This is the last of the feed you'll be getting until those nanobots deactivate. I'm gonna leave you as a dainty little flower of a dairy cow. Smaller than the rest in all places you'd want, except for that lovely udder of yours." He laughed as Chad vacantly mooed, then began to eat from the most recent bag. "Welcome to the rest of your life, Chad."
And with that, Spencer left the stall. After a few minutes of hastily finishing his remaining tasks for the day, Spencer jumped in the family truck and headed off the farm.
Upon hearing the truck zoom away, Chad wrenched himself away from eating any more. Ever since Spencer brought Ferdinand around, the primal fear of getting mated with that beast had caused Chad's mind to reawaken. He'd heard everything, and now that he knew Spencer was gone, he needed to figure out what could be done to ruin Spencer's plan.
