In this morning’s post, I intimated that I was going to attempt to monitor the progress of the hatching eggs using a weighing technique. I have found a less-intimidating equation, and thought I would share.
It comes to this: chicken eggs should, ideally, lose 13% of their weight between Day 1 and Day 21. I am prepared to take their word on this one. I am nothing if not trusting.
Take the total weight of your eggs on Day 1: 80.4 oz.
Multiplied by 0.87 to get weight your eggs should be on Day 21: 69.95 oz
Multiplied by 0.13 to get weight your eggs should lose over 21 days: 10.45 oz.
Divided by 21 to get desired weight loss per day: 0.5 oz/day
So, if I weigh again on Day 7, that will be six days, so my eggs should, ideally, have lost a total of 3.0 oz. If they have lost less, humidity is too high. If they have lost more, humidity is too low.
Your thoughts, please!
