Where did we go wrong? This was our first time trying to incubate. Set 29 eggs in incubator w/turner. On day 5 candled and discarded 10 eggs which were not fertile. Day 12 we candled again and could see some development but did not see any movement. Stopped turning on day 18. Temp kept constant at 99.5 and humidity 60% for the whole time. day 23, candled again, could see a very full egg but no chirping or movement. Decided to start opening to see what was going on inside. Sadly all were dead :-( had about 4 that obviously quit early on, 3 were non starters and the rest almost perfectly developed, 4 of which had got as far as opening the membrane into the air pocket. One was at about 14 day stage and had a very crossed beak and a deformed leg. The parents of these babies were, Pa, a white silkie and his ladies, a RIR, EE, BR, SLW & a Buff Brahma. Could the mixed breading cause this result? Was the humidity too high in the beginning? Pa, the white silkie was only 9 months old and his ladies were 9 12 months old, were they all too young to breed? We had noticed that the shells on our eggs had been very thick compared to store bought eggs, could the thick shells affect the absorption of moisture/humidity? Could it be they were too thick for the chicks to break out? There was no bad smell from any of the eggs so I dont think bacteria was the problem. I am going to try and post the pictures we took when we opened them in the hopes that someone will be able to identify a problem, I hope that they dont upset anyone, that is not intended. I would really like to try again so any advice from the experts out there would be much appreciated. Thank you.
