I have 12 laying hens and for the past three days not one has laid. They have fresh feed and water and a nice place to roost. We live in south tx the temp here is in the low to mid 80's right now. The only thing that has happened is that last weekend a stray dog killed one. They were out of their pen scratching around. One hen was inside the pen with the gate open. The dog got in there and killed her. She was the only hen in the pen. My husband was able to remove the dog. The hens continued their free ranging and seemed to be fine. They are all about 2 1/2 years old. Does anyone know what could be the answer to why they are not laying.
