I went to check my flock this morning and found 2 light Brahma cockerels dead and slightly squished. My favorite pullet, buffy, my buff Orpington was dead in the coop with only her feet and beak left.. my husband thinks it was a dog but I think a dog would have killed more and that they would be slobbery and not such clean kills for the brahmas. And why such a brutal kill for my buffy? Any ideas?
