These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Chicken Run
Alternate Character Interpretation: Is Rocky a Jerk Ass, who lead the girls on false promises and turned their backs on them only to have a sudden attack of conscience that prompts him to return, or is he a sympathetic man (or rooster) who was put into this situation by a goal driven chicken who would stop at nothing to get what she wants, and gets treated like a Jerk Ass even though he technically, never lied in the first place.
Edwina. Did she not tell anyone because she didn't want them to worry about her, or did she do it deliberately because she wanted to die?
According to The Other Wiki, the producers attempted to avert this by dropping a character from the early scripts named Nobby (who was supposed to be Ginger's little brother, and thus the Kid-Appeal Character) in order to avoid being excessively cute.
Award Snub: Despite critical acclaim, a determined campaign from Aardman and preference by a number of Academy voters, the movie failed to gain a Best Picture nomination. This would result in the creation of the Best Animated Feature category the next year.
Fridge Logic: Naturally, an egg will only hatch a chick if the mother hen bred with a rooster. Which means that all the chicks we see at the end would be either all Ginger and Rocky's offspring, or the guy ... ensured everyone's eggs would give them one. Although it probably plays by the fictional rule that an egg always hatches if it doesn't end up as food.
Well, Fowler might also have *ahem* contributed, though there's no indication that he's considered a Silver Fox by any of the hens.
Fridge Horror: What might have happened if the plane never got the Christmas lights hooked on, and Rocky and Ginger had nothing to pull themselves back onto the plane?
Wait a sec, wouldn't that door kill Mrs. Tweedy?!
Probably not, since she managed to survive the machine explosion.
What would have happened to Babs if the Tweedys hadn't switched to pie production over egg farming?
Nightmare Fuel: Mrs. Tweedy has been compared to Maleficent in terms of scariness, and for good reason. With her motivation being stereotypical greed, she could easily have become a comical Large Ham, but she...doesn't. Her lack of emotion as she carries out her plan is precisely what makes her so chilling. And then we have the climax, where she goes Ax-Crazy and maniacally tries to slaughter our heroes, arguably For the Evulz at that point. To top it all off, think about the film in relation to World War II; it shouldn't take long to realize that Mrs. Tweedy is an Expy of Hitler. Enjoy the movie, kids.
What makes it extra scary when she goes Ax-Crazy is when Ginger and Rocky discover Mrs. Tweedy holding onto the lights, she roars at them. Can't blame them for screaming.
When Ginger and Rocky get trapped in the pie machine.
The offscreen death of one of the chickens by axe in the beginning of the movie. You don't see anything but you hear the sound.
