I am so baffled. My hens are dieing. I've had a bad month so far. We let our flock free range. First our two roosters get taken by a predator. We're thinking a bobcat since it was in an area of trees. (I'm surprised it was the roosters and not a hen). A couple days later one of our friendliest hens was dead in the coop. That same day I brought home 2 young hens from a friend. About 5 days later, one of the new hens was dead in the coop. Then last night my son found another hen sitting on the ground so we put her in a xl large dog crate with water. My husband said she was alive at 6 30 this morning. I went down there at 730 to give her a warm bath (per someones suggestion) and she was dead. She was showing signs of being lethargic and had an aweful smelling diarreha. Other than the sick hen, they showed no signs of trauma. My son is so sad that this is happening to his flock. We've had them for beginning at 4 years ago and always hatched out a few every year, so they are all ages. I believe we are at 19 now. The weather has been warm low 90. but the evenings have cooled down to the low 70. The day the first hen died it was only low 80's. Hope someone can help us. thanks.
