Hubby and I watched this and really liked the concept, but we couldn't help laughing about the poor chicken trying to squeeze through (makes me feel a whole lot better about the size of my coop pophole).
There is also something ironic about having a metal guillotine type door SLOOOWLY lifting above an outstretched chicken neck.
I have to say, it made us feel just as impatient as the chickens waiting for the door to open, but, hmmm..., if it could be improved upon????
My sons would love to try to figure something like this out. I'll have to put them onto this as a homeschool project.
Our favorite so far is Nifty-Chicken's invention with his daughter explaining about racoons. My kids still imitate her cute little, "..and they don't do it!" (speaking of the racoons who can't get in).
Our door moves that slowly, too, but the chickens don't force their way out. They just wait for it to open. It's good for it to move slowly, so the chickens don't get scared or injured, when it's closing at night.
Were there more chickens in the coop that didn't come out? I wonder if that door was just installed and the chickens weren't used to it, yet. Maybe I just have more patient chickens.
