Queen Bees

I have found a really easy way to get the queen bees.Go to the store across from the warehouse and there should be books.The one to the left of when you enter closest to the exit is a book that shows colors over zombies heads.Walk around outside until you see a zombie just standing with a green instead of blue head.Kill it for a queen,repeat until you have enough.I put it here because more people would see it if it was here.
