not hatching well

[hatchcrazzzy]

i need some advice my eggs are taking 22 to 23 days to hatch but the temp is always 99.5 i do turn thehouse heater down at night would the night temp have to do with them hatching late .should i turn them an extra day?also my hatches are now down to 50% and i was hatching 95% .i also checked a couple of eggs and the chicks were full term and ready to hatch .they just died in the shell.my last 3 hatches have been this way

Sounds like the typical issue of thermometer is not giving an accurate reading. You either have to calibrate it or just raise it a degree to 100.5. That should improve your hatches to on time. I would imagine the high temps are causing some losses as well, so that may explain your reduced hatch rates. I would fix the temp first and see how it goes.
