Well we had 6 leghorn eggs under a hen she disgarded two and killed the only two to hatch. When we eggtopsied the other 2 they had died around 18days. We had 4 eggs in the incubator 2 marran and 2 light sussex. We just tossed them at 23 days they were stinking so no chicks just black gunk! They did look like they started to grow but died early on. We are gutted. I now have 6 Cream crested legbar eggs set in the incubator but I am not hopeful. They are due 10th August. I am sooooooooo Oesdog - my hands stink of gunky gone of eggtopsy!!!!!!
