They just started laying on Tuesday and I have been getting 1-2 eggs per day from 6 hens. There is only one male that made it through the incubation and constant predator attacks. In total I have 7 and I have not broken one to check for fertility. What are the odds of them being fertile with a 1-6 rooster to hen ratio? I am a science teacher and school ends this week. I helped a motivated student build his own incubator, after we did our own classroom hatch. I would like to collect all these eggs and give them to him before the last day of school so he can continue the hobby after he graduates.
