In the scene when the actors walk into a chicken warehouse, they filmed in a real warehouse in Oklahoma. It was filmed in separate sections with bloody prop chicks and real chicks which was edited together in post so it appears some chicks are injured when the actor drops a crate on the floor. Chicks are carried to set in transport crates with cardboard lids and air holes by the trainers.There are four 10’ tables stub in two rows in the room with stacks of crates at the end of each one and in the corners of the room. The chicks are divided up to give each actor and background person about 15 chicks each to sex. They all have three crates each, one for all chicks to be sexed in the center, and one on each side to put male and females respectively. All background extras are experienced real chick sexers from Continental Poultry Services in Arkansas, where the chicks were hatched.
On action, the actor picked one chick up at a time one up, made light squeezing action to simulate removing poop from vent over lined coffee can, then tilts the chick to show the two actor kids inside the vent.
All chicks were returned to holding while cameras were setup for next scene and rotated into the scenes by keeping up with the cardboard carriers.
In the scene where the two kids hold chicks in the house, prior to filming the trainer instructed the children on how to hold chicks.
In the scene where the kid throws a rock at the snake wrapped around a tree branch, the black rat snake was transported to set in a plastic carrying container with air holes, a water bowl, and bedding. They placed the snake on the tree and stepped away. The director got the shot of the snake on the tree and called cut.
