I only count the eggs that make it into the hatcher. I do not count the others that do not make it in for one reason or another.69 eggs into hatcher on wednesday night46 hatched0 deformitiesI call that a 66.66% hatch rate and still more coming.mike
isn't it cheating if you don't count all the eggs you first put in the incubator? if you put in 100 eggs and only 75 hatch you have a 75% hatch rate.scot

If someone ordered eggs from you, let's say 100. He puts all 100 eggs into his incubator. He now candles the eggs after 2 weeks and finds no fertility signs on 10 eggs. He now has the possibility of only a 90% hatch rate in his incubator am I correct?Now let's assume, all goes well during the incubation period, proper temps/humidity. It is now time to move the eggs to the hatchery. We are now working on the possibility of a 90% hatch rate, am I correct here?The 90% hatch rate is scheduled to hatch in 3-5 days into the last incubation cycle. Proper temps and humidity have been accomplished. The hatcher/hatchery has not been open at all during the hatch cycle. No loss in temp setting, no drop in humidity settings.After the last day of the prospected hatch, you notice 10 more eggs that have not hatched/survived. 3 died in the shell prior to piping and the other 7 died during the exiting of the shell. Correct me if I am wrong but we are now down 10 more leaving it a possibility of an actual 80% hatch rate in a 24-hour period.This leaves the actual hatch rate in a 24-hr period as 80%. All chicks that leave the hatcher/hatchery after the drying period, whether 12-hour or 24-hours even if deformed still counts as an actual hatch rate.I base the sale of my eggs on the actual hatch rate as I have stated above. What I set in the incubator is the actual start base line. I do not start to eliminate eggs on the initial set, due to infertility.If I state a 70,80, or 90% Hatch rate, this is based on what the actual egg count set and hatchery hatch.StevePheasant Hollow Farm.
Well let me clear the confusion here. Fertility Rate=All eggsHatch Rate=Fertile eggs
We calculate our hatch rates the same as Pheasant Hollow Farm.Discounting what was infertile misrepresents a fair ratio, imho. BabsCountry Egg
