I need some advise on hatching eggs. My son in law has Ruen duck eggs that are 6 days past hatch time. He tried to open one last night and the membrane was stuck to the chick and when he pulled it tore the skin and it bled to death. The eggs are still moving and he wants me to try to open them. I am afraid if I don't try something they are going to die in the shell. What would you folks do? No pips just movement. Please help. John
