My first time hatching - I had broody hens so I bought some 'fertile' eggs, by day 14 some were and are still viable, 4 to 5 more days now and I'm expecting them to hatch. I'm nervous about the last 3 days of hatching, I've also bought an incubator which every article I've read on incubation says not to turn the eggs in the last 3 days of the incubation period. Will my hen's instincts kick in? Will she "know" not to "mess" about with them LOL. I know this may seem odd but it really does have me nervous and curious.
