Rocky would know what popcorn is and how to make it because of his past at the circus.
Fun-Land Farms:
Seeing the almost ridiculous level of security in Fun-Land Farms makes a lot of sense when you realize Mrs. Tweedy is in charge. She found out the hard way that chickens are capable of pulling off farm escapes in the first film, and evidently has learned from her mistake of underestimating what they can accomplish. The security's not in place to keep unwanted guests away, it's there to ensure that no chicken gets out.
The positive and happy aesthetic for the imprisoned chickens adds to this; the prison camp was something they would want to escape from, but this place being fun and seeming to be paradise keeps the chickens content and not wanting to escape.
The mind-control collars creating amnesia for anything outside being happy and loving Mrs. Tweedy work very well to keep things that way. The memory loss ensures that chickens who come in together can't team up to escape, and it also ensures that none of them will ever make the connection between another chicken "winning the contest"/"going on holiday" and never being heard from again.
The new setting is a lot more high-tech and has a much sleeker aesthetic than the ramshackle egg-farm-cum-POW-camp the first movie was set in. But it makes sense once you remember the first movie was an Affectionate Parody of World War II action movies from the 1960s; since this movie's set a few years later, they've moved on to parodying the next great action movie trend: older Bond-style spy films, wacky gadgets and secret lairs and all.
This is also reflected in Mrs. Tweedy’s redesign; her overall look is reminiscent of '60s supervillains.
People were quick to notice that Mrs. Tweedy’s new appearance features her wearing more makeup and generally having a glow up from the first film. However, in the first film she lived on a farm and didn’t have a big profile. With her now being one of the big names in a big business, it makes a lot of sense that she’d put more effort into her appearance, as she’d want to make a good impression on any guests or potential business partners.
Also, the other reason why is because the impact of the door at the end of the first film may have broken her face. At some point between the first and second film, Mrs Tweedy had plastic surgery which not only repaired her face but also made her younger when you compared her face from the last film to her in this film.
Considering Mrs. Tweedy’s behaviour towards Reginald seemed to indicate she might have been prepared to accept more than just a business partnership, it could even be possible that she was deliberately trying to make herself appear more desirable.
If you notice, Dr. Fry is even more loyal to his wife than Mr. Tweedy was. For example, contrast how when Mrs. Tweedy first appeared and Mr. Tweedy (along with everyone else) are fearful of her coming outside and noticing a chicken outside the fence with her first appearance in the second film where Dr. Fry is actually happy to see her come down the stairs. This was probably intentional on Melisha's part. Other than his wealth and mind, she more than likely gave him a shot because the more happy he is at assisting her goals, the less likely she'll have another barn door push incident. It turns out she was right, as Dr. Fry didn't have a hand in her final defeat (in fact, he tries unsuccessfully to get her out of there).
It's shown that the chickens don't recognize or remember their own friends and family while under the influence of the mind-control collars. Given that the human controllers had no idea what the higher levels did yet, Mrs. Tweedy turning Ginger's collar up to eleven could have permanently damaged her brain, possibly leading to her never being able to remember Rocky, Molly, or her friends.
Dr. Fry presumably had to build and test several iterations of the collars before they worked as they were supposed to. How many chickens did he and Mrs. Tweedy experiment on, and what happened to them? It's not hard to imagine a faulty or malfunctioning collar killing the victim or leaving them brain-dead.
They’d have also had to presumably not only develop the recipe for the nuggets, but it’s possible that the nugget processing machine had to go through changes to make it as efficient as possible (possibly in conjunction with how much influence the collars were having too). It’s very likely that a number of chickens would have been killed just as test runs for the final product.
Does the collar keep working even as a chicken is being ground up for nuggets, or are the victim's last moments a sudden shock of agony as they wake up from the brainwashing to the nightmare of being ripped apart? Given that it's likely that the collars are removed right before they're ground up, it's probably the latter.
A lot of the chickens that ended up being slaughtered in Mrs. Tweedy’s first farm were probably unhappy and scared when they were taken to the chop. She may have had first hand knowledge that their meat wasn’t the best quality, which could have given her the idea for the collars.
It was very lucky that Reginald's "proposal" to Mrs. Tweedy was just showing her the dipping sauce. If he had asked her to marry him (and Melisha's reaction indicates she expected a proposal), it wouldn't have ended up well for him; he just would have become Henpecked Husband #3. Melisha Tweedy Has a Type...but that "type" is more "loyal, useful minion" than anything conducive to a loving relationship.
Chicken #314 (and any other chickens who ended up being victims of the nugget processing machine) may have had friends in the groups they went in to Fun-Land Farms with, but then the collars made them forget about each other/their friendships. Once the collars were disabled and removed, it’s possible that some of the chickens noticed their friend was missing - and did they ever find out how horrific her end was?
There was a notable amount of security and other workers in Fun-Land Farms; it’s possible that they may not have been able to escape in time when the farm was destroyed.
