Hi, Just suffered a big tragedy with our flock. Our house is being painted and one of the painters left a gate open, letting one of our neighbor's dog into the chicken area. We had 15 killed and were pretty devastated. Instead of refrigerating their most recent eggs, I have kept them out in hopes that one of our 12 hens left will go broody. (don't have an incubator, have always used broody hens). . We really want to hatch some babies from the hens we lost to remember them. How long do I have before the eggs are no longer viable and won't hatch? This happened on Thursday 4/2. Also, is there a way to encourage our hens to go broody? It usually just happens when we don't collect the eggs.... Thank you so much for your help.
