Just wanted to say that we are in the same situation. Our coop is filled with earwigs. When we open the window, 20 or so will run out of the gap. ONE chicken is interested- the others are just unimpressed. You can easily find them buried in the shavings. I picked up the paving stone the water was on the other day and about 50 of the little suckers ran out. SO GROSS. I'm hoping as my chicks get older, they'll love them. I HATE them. I keep tossing them at the chickens, hoping to spark some interest. Our chickens free range, so they don't spend a lot of time in the coop itself.
If they are all ear wigged out- I'm going to start freaking out. There must be millions!!!!
