Continuity mistake: When Chicken Little slips on the acorns, you see he has slipped just before a sign. But when he gets up and starts chasing the bus, the acorns are not there.
Continuity mistake: In the scene where Chicken Little lends the alien baby, Kirby, his handkerchief, after Kirby blows his nose, it sticks to Chicken Little's hand. Chicken Little then wipes the hanky off his hand on to the grass. In the very next shot, the hanky has disappeared, and never shows up again.
Continuity mistake: In the scene where Chicken Little brings his friends to see the panel in his bedroom, there is a pendant behind the pig's right shoulder. After Chicken Little says, "OK, subject change", the pendant is not there, but there's a door instead. There would be no room for the pendant to have been there in the first place.
Continuity mistake: In the scene where Chicken Little and his father are being held up for incineration, there is a shot where weapons are surrounding them in a 360 degree angle. Then it cuts to a shot with them looking towards the alien with the big holographic face, only the weapons are surrounding them in a 180 degree angle behind them.
Other mistake: When the pennant game is being played, Chicken Little's team is down by two runs with a score of 14-13, but if you add the score up off of the board before Little's two run hit, it equals 15.
Continuity mistake: From the time the panel falls from the sky the second time and into Chicken Little's room, it changes sizes many times. For example, it is large when Chicken Little leans it against the wall before his friends come to see it, but small when Fish holds it in front of his face. It is large again when Fish hops on it for a ride up into the sky.
Continuity mistake: After Foxy Loxy throws the acorns out the school bus window at Chicken Little, he falls over and watches the school bus drive around the corner and past the white town hall. In the next shot, however - an aerial shot of the town - the bus is seen passing the town hall a second time.
Continuity mistake: In the scene where Chicken Little sees the star that gets bigger until it hits him, you can see the shine of the small star on Chicken Little's glasses and on his eyes. In the next shot, when the star gets bigger, you can only see the shine of the star in his glasses-and not on his eyes.
Continuity mistake: In the scene where the town's "people" follow Chicken Little to the baseball field to see the why he rang the bell a second time, Chicken Little is talking into the camera and there are no rocks on the ground behind him. However, three rocks in a pile appear in the next shot just in time for Chicken Little to throw them at the invisible space ship.
Continuity mistake: When the panel falls on Chicken Little the second time, when he's in his room, it looks like the black sky with one star in the middle. In the time it takes Chicken Little to open his eyes and see the panel and his father runs upstairs to see what's wrong the panel doesn't change. Every other time they are moving the panel against different backgrounds it changes almost immediately.
Factual error: When Chicken Little is in his bedroom, after he scored during his baseball game, he looks into the spoon he is using as a microphone to see his reflection. He looks into the side that is curved away from you. When you look at that side of a spoon your reflection is upsidedown, but Chicken Little's was right side up.
Continuity mistake: During the opening sequence, when the water tower is knocked over, water splashes from the bottom. Yet when the tank starts rolling, it is a complete sphere - no hole for the water to get out of.
Continuity mistake: Towards the beginning, when Chicken Little is going to school in his underwear, he ties a bottle of soda to his back in order to "fly" into the building. First of all, where did he get the rope? And second, when he lands in the school the rope and the bottle both disappear.
