We started out with 6 chickens- born 4/25/12. 2 each of Americaunas, RIR and Black Australorps. They have all been healthy to this point-with one exception- only 2-6 eggs per week. I don't believe the Americaunas are laying at all because we've only seen one egg in the coop and it was half gone and blue. Monday when I got home from work, one of the Australorps was laying underneath the waterer in the run, dead and stiff. Her vent looked like it had exploded. We thought it was because she was eggbound and the other hens pecked at her backside. Tonight, we found one of the RIR hens dead in the coop with an egg stuck in her vent. Not sure what or why this is happening.....We feed them a good organic feed and fresh water. We clean the coop every Saturday and put fresh hay in their laying boxes and pine chips on the coop floor. If anyone has seen this happen to their flock, please let me know if there is anything we can do??? We don't want to lose any more of our ladies..
