2 Turkeys and 7 chickens ... Opened up the last four eggs, 3 turkeys and 1 chicken.. all fully formed but never internally piped, heads in correct position on all membrane normal (not to much fluid nor to dry)
Disappointed and second guessing myself on what I may have done wrong, temps perfect, dry incubation and except for the one egg all air cells normal... The only thing I can think of is these turkey eggs were the first eight laid by these two (at the time) 9 month old hens, The hens are 10 months old now. but eggs seemed large enough, chicks not to big for shell...
Second set goes into lockdown on Tuesday morning

eight Turkey eggs and I believe 6 chicken eggs
Seems I had a way better hatch rate hand turning last year and keeping the eggs out of the turner
