I went out to feed this morning a little later than usual to find one of my hens on her side and barely alive. I could see no signs of predators and their coop is very secure. I picked her up to bring her in the house and she died in my hands. I have had the birds since 4/15 last year (Day old hatchery chicks) This is the first one I have lost. I couldn't feel anything in her abdomen. Her crop was completly empty. I did not do a necropsy and my husband took her out to dispose of her. My chickens are well fed and cared for but not pets. The egglaying has slowed lately. Out of 20 RIRS I was getting only a dozen eggs a day.Last summer and fall I was getting 18. The hen was lowest on the totem pole and had her feathers picked on her head. I am wondering if the stress of constant harrassment from the rooster and the more dominant hens could have had something to do with it. I am keeping a close eye on everyone else to check for any symptoms. She was fine last night when I fed them and showed no signs of labored breathing, discharge or lethargy. Her vent was a bit prolapsed when I found her. any advice would be appreciated. Thanks
