We have a backyard flock that consisted of 3 Easter Eggers, 2 Bards, and 3 Buff Orphingtons. They all stayed in their own breed groupings, and all was well. A hawk killed one of the Easter Eggers, and we showed her body to the flock, and all was fine. But then our neighbor's Alaskan Malamute killed two of the Buffs, who, btw, were the friendliest birds I've ever owned. I was not home when it happened, and the neighbor threw the bodies away, not knowing to show them to the other Buff first. Now that Buff has been grieving for over a month. She won't come out of the egg box, and heads back every time we take her out. While she is out, she walks around the yard crying and squawking, evidently looking for the other 2 sisters. She is losing weight. She sharpens her beak like a nervous tic. Occasionally she will be with the Easter Eggers, who readily accept her, but I see no progress and worry her weight loss and brooding are going on too long. Any advice? thanks.
