My Coturnix quail have suddenly stopped laying. I haven't had a single egg in a few weeks. I don't think it's trauma. We had a raccoon issue a few weeks ago and even after losing 8 birds, the girls continued to lay without issue. We took care of the raccoon too. I did run out of high protein feed a few weeks ago and no feed store had anything higher than 16%. I've upped the protein again. I've given a 29.65% protein supplement along with 22% meatbird crumbles. Still no eggs. I've left a light on at night for a few nights, still no eggs. I'm in PA, it's only August, we should have enough daylight shouldn't we? Could there be any other causes?
