Most likely. I stupidly tried to candle a couple of my quail eggs. I should know better by now, they're just too fragile. When I was moving them, I collided one button quail egg with another and dented both. I have tried a repair with neosporin and waterproof surgical tape, but I have my doubts. They are due to hatch around July 30th. The good news is, I candled 5 of the Coturnix eggs as well, and 5 of 5 are developing and alive at this point.
