I just lost my Ameraucana! She was just dead on the coop floor. I do have three roosters in the coop, but didn't think there would be an issue. My Easter Egger roo picks at the Splash Andalusian roo's comb, but I'd never seen him pick on the Ameraucana. I was on the fence if my Ameraucana was a boy or a girl - but it didn't look hurt when I took her out of the coop. Is there anything I should look for in the other chickens to see if they are actually ill? I'm so concerned that they're sick. Do chickens just sometimes die out of the blue like this?
