About a day and a half ago our chickens suffered a hawk attack. As far as we know, the hawk didn't make contact with any, but we couldn't find one of our welsummers after the attack until dark when we found her in the coop. The next day, she was slow and lethargic, but still following the others to a degree, not scratching. We picked her up and her wing just drooped, and wouldn't eat. We put her aside from the others for the night and this morning she was dead. We did notice a greenish and watery dropping from her yesterday as well. Could this have been salmonella? Maybe she did suffer an attack and we couldn't see the injury? I'm at a loss on this one. Before the attack she was sprinting around the yard. Any opinions on the matter?
