Day 16 Embryo Development - scales, claws and beak becoming firm and horny

Comments: We decided to weigh the eggs as another way to check how much moisture is being lost in each egg. All eggs have lost between 5% and 10 % of their original weight. This is more reassuring than candling and looking at the air sac size. So we decide to bring the humidity up to around 50%. If too much moisture is lost, the chicks can't get out of their shell when hatching. How does the hen do all this??!!
