This morning when I opened the coop to let all of my chickens out i noticed that my biggest japanese bantam was dead in the nest box. It didnt have any signs of being pecked and yesterday it was totally healthy. Yesterday we had an unexpected rain downpour and the bantams hid under the coop instead of jumping up in it. Could this be the reason he died? We have just started letting the bantams sleep in the coop with my full sized breeds could this be the reason? I just have no clue. It was so unexpected!
