Weekend projects: Chicken Squisher 3000

Does the product live up to its name? By which I mean, how often will chickens get squished (or more likely, maimed) because they fail to get out of the way of the door as it closes?

Power windows in cars often come with automatic reversal mechanisms, which are designed to detect obstructions and prevent the window from closing on them. I don't see mention of such a safety feature here, though.

Maybe making the Chicken Squisher 3000™ close very slowly would reduce the likelihood of a squish event? In the video, it's not like the door slams shut, but it's not slow.

Or maybe chickens, dumb as they are, have quick enough reaction speed that the danger of squishing is negligible.

Chickens are dumb, but they still have plenty of natural reactions. If you throw something at them, they don't just "take it", they'll try to dodge. I imagine this speed is absolutely sufficient.

That being said, if this is a problem, you could just switch to ducks. As my rancher friend often says "ducks are much better at not-dying."
