I found a dead mouse on the ground in the yard. My birds have been free ranging all day. I have guineas and BSL hens (and 4 cockrels but they don't range that far out yet.) The mouse was floppy and wet as if it had been "mouthed" by something but there were no wounds or blood. Could this have been the birds? I can't imagine anything else that would just kill a mouse and not eat some or all of it. I have heard that chickens and guineas will eat baby mice but this was an adult. Do any of you have birds that make good mousers?
