My Blue Cochin hen was taken this morning by a dog or coyote. I went out to check on them a few hours after I opened up the coop and run, and the chick was running around in the run without her. Searched all over for Mama, couldn't find any feathers, but Bob found what look like pretty good sized dog tracks, and there is no sign of the Cochin hen anywhere, so we are assuming she is eaten

. Put the chick in the brooder, put the two Sussex back into the run and closed it. Will be restringing the electric fence today - now that something has found them they are in danger, and we'll keep them in and watch for something to return. If I determine it was a dog belonging to a neighbor up the road (in other words, if it comes back and I am able to track it back to its house), I will visit with them immediately and tell them what happened, and that we are entitled to shoot their dog if it comes back. I don't know that it was a dog, as I said it could have been a coyote, but the prints look pretty big.
The electric would not have saved her, as I would have unplugged it when I let them out anyway, but it will protect the two hens now locked in there, as I expect a return visit now that the food source has been discovered, and without electric whatever it was will try to dig into the run. The only thing that would have changed the outcome is not having let them out this morning. Without the chick to protect, she may have gotten away, the other two appear unharmed. I hesitated before opening the run this morning, and wish I had followed my hesitation. Broodies are well known to protect their chicks to the death, and I believe that is what happened. I will be rethinking my management, and may restrict free range time to time I am outside with them. I hate that idea, but really hate losing a good hen even more.
So bummed. First time I've ever lost a chicken that was not confined to a run.
