No goats. I was optimistic, since I caught her like this today:
Found another dead chick in the coop. It's the Wild West out there I guess. When I went out earlier there was a chick with a bloody eye. I held it for a long time while I decided if I was going to intervene or not. Ultimately I decided I'm not meddling (too much) and put it back. It was the third dead baby.
So now Ruby has four chicks!
And Bonnie has three! And one egg that she is VERY determined to abandon. But it's externally pipped and seems pretty vigorous, so I put it back under her for the third time today. Because I can't just quit meddling.
Hard to say who killed the third one, because it was in the main coop. Could have literally been any chicken. I think Ruby is doing a good job though.
