Second round of 6 eggs in the incubator and once again I have only gotten 3 to hatch. The chicks have died in the shell. They are fully formed but the yolk had not been absorbed. I read that the yolk begins to draw in starting on the 18th day. I am getting 11 out of 12 to hatch with the barnyard mix eggs that were put in with them again. Is there a chance that the roo is tufted and they were plucked before I got him? He was in a small pen with 3 other boys. That still would not explain half of them dieing? My incubator has a fan. I am keeping the humidity at 35% and then 40% at hatch. The air sack was quite large when I opened the eggs but I also let them go 24 days before giving up.
Any thoughts?
