I loved having chickens, but sometimes you can tell they're little dinosaurs. One time I was doing something near the chicken run, and all six of them suddenly went quiet and dead still. Then a wasp flew through the run and one of the hens jumped about 2-3 feet off the ground and knocked it right out of the air. Another hen ran over to where it landed and ate it. It was all over in about 15-20 seconds, the birds went back to acting normal and I'm just standing there going, "Damn!".
One of my hens came up to me as I stepped outside, but instead of following me around, she leaped at something to my left. She shredded apart a 4-inch long mantis!
You gotta be careful though because sometimes they get a craving for the high taurine diet and start eating their own eggs. Incredibly hard problem to fix once it starts.
