Lost one of the Brown Leghorns tonight.

I always let the dogs out and bring them in prior to letting the chickens free-range in the evening. When I let them out tonight, I didn't know two leghorns had flown over the run. When I let the dogs back in, I noticed some feathers in the water bowl after Jack, our Lhasa Apso mix, got a drink. Yep, found one of the leghorns in the backyard by the corner of the deck. Another had flown over the yard fence to escape. She stuck close to the coop after coming back in. Only 3 white egg layers now.
