Had a couple hatch last year that had bellies so big they could not walk and someone in the peafowl group suggested it was because the egg didn't lose enough water? This subject interests me, so please, let me here what you're thinking!Perhaps 13% is the threshold of how to get the biggest chicks or ducklings out of each egg. 16% may have good results, but the chick won't be as big had it only lost 13%?
Discuss.
