Yes, Vital Farms admits they do not keep roosters. Their eggs won't be fertile.
Look for cartons of eggs marked 'fertile.' The mark may be in small print.
Rock Island fertile eggs may be fertile, but they have a low rate of viability because of washing. Safeway carries them. Trader Joe's also carries fertile eggs. The best results I have seen (from fertile grocery store eggs) was a carton sold at a local organic grocery which was a week old, kept in a cooler, and came from a farm called Red Rose Half Acre, 20 miles away. Eleven out of twelve eggs developed.
