I incubated 36 eggs. Yesterday they started hatching. Blood was dripping from the eggs. I helped several of the chicks out, they were sufficating in what look like a blood clot around them. The couldn't break through this thick skin. This was my 3rd brood hatching. I had no trouble with the first 2. Does anyone have any idea what might of went wrong. It was so sad. Out of 36 eggs I had 17 live. One of them are crippled. They all don't seem to be very strong or healthy. It has been a very stressful and sad experience. I stay up all night to take care of them, but I still lost some.
