I need some advice from experienced hatchers. I'm hatching maran eggs, they were shipped. I'm weighing them to judge humidity because they're difficult to see anything. The breeder I bought from recommended 30-35% humidity. I calibrated my hygrometer by doing the salt test and after 24 hours it read 73, so I've been trying to keep my humidity between 27-32.
Well I weighed today (day 6) and holy cow I think I have a problem. If I'm understanding the weight that should be lost as 12%, so I multiplied each egg's weight by .12 and then divided by 3 to calculate how much weight should be lost each 6 days.
Well one egg started at 46.9 and today weighed 42

, most of my eggs lost 4gms in 6 days a few lost 2gms and 2 lost none.
Any advice would be appreciated obviously my humidity is far to low. Have I completely screwed these eggs or can this be compensated for?
Also should I post a separate thread for this? I have found good responses here.
