I think I'm ready to admit that something is just not quite right with my incubator & hatches. I just read this article on possible issues, http://edis.ifas.ufl.edu/aa204. In general, I have 50% or lower hatch rates. On shipped eggs it's often 1-3 chicks from 12+ eggs. This has been super disappointing because eggs that were "affordable" become one or so very expensive chickens. Here are my details as they come to me: Brinsea w/ auto turner - less than 1 yr old Have checked humidity w/ two different hygrometers, both of which showed to be off by 14 & 25 points respectively when tested w/ salt in baggy test for accuracy. As far as figuring in those readings when checking the humidity - it seems to be within normal range. I'm curious about dry hatching & what that means. A friend w/ the same incubator has suggested that maybe the temp is slightly high because: had excellent hatch w/ runner ducks, seem to hatch a higher than normal rate of males, most seem to develop to the last few days then die, have hatched 4 this summer with toe deformities (though 3 of those came from a breeder who has had past issues w/ her birds having the exact same problem - so that may not be due to me). Temp reads 99.6 on the glass thermometer. Just hatched 12 eggs from a breeder right down the road - so no rough handling by PO, 8 of 12 hatched. This breeder has the exact same incubator and I follow her routine to a "T". She puts in 12 eggs & gets 11 healthy chicks.
