I have never had a problem with bob white quails before but I recently sold mine and I got some more full grown ones. At night in Ohio it it getting cold but my first flock was good with the cold and I put them in at november for the 2 years I had them. But these new birds did fine until the cold weather and about four died now I have about 8 left so I don't like to take chances so I moved them inside my barn with a heat lamp on them at night. Why could they be dying aren't Bob whites sopossed to be good in the chilly weather. The ones I had before were butler and now there northern bob white. They always have food and water. The coturnix quail are doing better then them I am surprised. And any other bob white care tips would be helpful I just want to know everything about these birds for their happiness and mine.
