I bought a dozen hatching eggs from someone on Craigslist. $20, and 100% were fertilized. I bought 2 dozen (received 28) from a show/breeder. $100, and only 56% were fertilized. With 2 quitters, I only have 16 out of 28 eggs going into lockdown this weekend. When buying hatching eggs, approximately how many fertilized eggs should I expect to receive per dozen? I’d like to have a better idea of how many I should buy next time. Thanks!
