In the past I had ONE really good broody hen. She was half sylkie and the sweetest hen ever. A great mom. She was fox killed along with *all* of my all organic flock (except for a rooster) so back to new conventional girls and raising new babies. Now All I have are two reds, and my half sylkie male. The girls will NOT sit on eggs. No matter what. No matter what season. I know these eggs are fertile so I bought a small incubator - yet none of the eggs will hatch out. About 1/2 to 2/3 of the eggs (at bare minimum) - when tossed out after way too much time, show lots of internal development (all the way to feathers) but nothing ever hatches, They just die and rot and go green inside the shells. I have no idea what I am doing wrong.
