... well, that is, all except one, who is alive but not standing too well. He lost all his tail feathers and his back is bare and has bite marks. The other 12 are dead. My mother saw a dog walking across the lawn with a chicken in its mouth, and she went out to look and found 11 dead chickens and this one still alive but mauled. She described the dog as a long haired dog gold/brown colour with a sheltie type look or a mini collie. There were feathers all over the run, but the 10 remaining hens all looked pretty much intact, so I guess he must have got them by the neck? The two roosters were the only ones that seemed to be really mauled, including the one alpha (dead) and the one that is still alive, but can't seem to stand. Does this sound like something a dog would do? Does it sound like a dog, to kill them all and then take off with one? My guess is that he went home with the one, and his owner saw him with a dead chicken and locked him up. Otherwise why wouldn't he have come back for more? Is it normal for a dog to just kill them? It's a very sad day here. The one that's still alive is a beautiful cochin. And I just sold two young roosters recently. And we raised most of these chickens from eggs. We had some lovely hens and the alpha rooster was a perfect RIR gentleman. I'm so sad. I'm trying to find out where the dog of that description came from. I've never seen that type of dog on my property before but there is one not too far from here. I'm going to go for a walk tomorrow, and will keep an eye out to see if it comes back, with camera handy.
