My Coturnix breeder groups have started losing feathers--there are feathers everywhere! They also have stopped laying. It's cold where we're at and they're on 30% protein feed so I don't really know what's going on., I also inspected them & they have no lice or mites--they're also drinking & eating okay. The only thing I could think of is stress--we moved them from the garage to a Quail Condo my husband built outside. The temperature difference is about 20 degree. Should I be worried about internal parasites? Also, we just brought them back into the garage in wire cages.
