A friend of ours gave us 2 dom hens and a dom roo during the time we were gathering eggs for our first hatch.We put a few of them in the bator and a couple of days later, during breakfast, we noticed that the dom eggs have blood stringing through them, in the white, too.No, they're not meat spots. We didn't candle the eggs, and are wondering - will these even hatch? Are they defective?Are the hens too old? We've had several of the other eggs hatch, and are on day 23 - no doms yets. Thanks so much in advance!!!
