Dang-it ! A cyote or something came in when it was hot a day ago and picked off three hens. I let them free range all the time and never had any issues but , I let the dogs in cuz they were so hot (they're getting older and the heat seamed like it was getting to them ) . I guess that was the opportunity they were waiting for. Argh!!! I feel so dumb, and I hate that I have to keep them locked up now. Two of them were really friendly too.
