Bunch of eggs due to hatch on Sunday. Weighed them today as I put them in lockdown. They have all lost about 6 grams. The initial weights of the eggs ranged from 33 to 42 grams. This is about 14-18% weight loss. Is this too much? I know you can't correct this in only 3 days of lockdown, but should I really crank the humidity to prevent more weight loss? Thanks!!
