I hope you can identify the person once you catch them- perhaps then you can get back the ones previously stolen!
I'm so sorry you lost any- it's definitely making me get moving on my locks- I never put the hasp on and haven't gotten around to it...and I live in the middle of a busy neighborhood with lots of foot traffic.
My dogs don't sleep outside, or I'd be less worried, but it's too late to train them to be okay with that- never slept outside a day in their lives.
I might just set up my own chicken-cam...I think sometimes I ought to have a lot more eggs than I do, and it's odd for them all to take the same day off...
