Dear all, A week ago I started my very first incubation project. Yesterday (day 7) I candled the eggs and results are very disappointing: only 5 eggs out of 21 show signs of development. The other 16 were clear with a moving yolk, not one vessel or blood ring or anything else could be seen. I would like to know what the problem could be. Any help is appreciated. Here the details: I bought all the eggs from the same breeder: 13 araucana eggs (quite small), 5 brakel eggs (pretty large), 3 vorwerk eggs (average in size). I picked them up myself; they were transported in cardboard egg boxes placed under the seat in my car. As I arrived home, they were kept in the house at room temperature (20-22 °C) for about 20 hours. After that I cleaned, sanitized and marked them with crayons. I put them in the cold incubator and than I turned it on. They lay on their sides. I started turning on the evening of the second day and turn them every 12 hours in alternating direction. I have a home made incubator equipped with a fan and automatic temperature control. I checked it very often and temperature and humidity values were ok every time. As already said, I candled them on day 7. All 3 vorwerk eggs are developing, but only 2 of the 13 araucana eggs and none of the 5 brakel eggs. The developing eggs lay scattered in the incubator, so I think their place in the incubator did not effect the growth. What do you think? Did I something wrong? It is problem due to shipping damage? Or maybe I just got wrong eggs and its not my fault at all?
