I had 4 black silkie eggs which I incubated successfully. Three hatched day 20, one early morning day 21. The forth was last to pip and didn't til morning day 21 when the third hatched. It made it think a small attempt at zipping some hours later in the afternoon where it enlarged the hole a bit. I left him to it and kept the humidity up. I checked on him in the evening and he wasn't any further along but peeping occasionally. I picked a bit of shell away but I could see blood vessels in the membrane so I moistened around the hole (careful to avoid his nostrils) and left him to it. I checked on humidity, keeping it high and before bed just now I checked again. My heart sank when I saw he wasn't peeping at all and when I touched his beak he was unresponsive. I peeled back a little shell to reveal his eye which when I touched around it, was also unresponsive. There were still blood vessels clearly there but I couldn't get a response at all so I assumed he was dying or dead... so I removed the shell as he was obviously going or gone? The membrane had alot of blood vessels in it, he bled and he had a small blob of unabsorbed yolk on his belly. He was completely limp but did twitch one last time before he was definately gone. What did I do wrong for this chick? It seemed strong enough and was very vocal before. Could I/should I have helped earlier even though there were many blood vessels? What can I do in the future? This is horrible. I never want this to happen again. :'( I feel absolutely awful.
