This is our first hatch - we put half in the 'bator and half under a hen. We've had 2 from under the hen - one had membrane stuck to the whole body when it came out and lost a lot of blood - seems to be doing okay. Now we have a second one from under the hen - pipped but no progress. This time, I peeled away most of the shell and very gently peeled some of the membrane with sterilized tweezers, avoiding the main vessel (could sort of tell where it was). I put her into the 'bator and she tumbled out of the shell almost right away but there's a big puddle of blood in the shell. What I'm wondering is, how common is this and how often do chicks with this issue survive? What should I have done differently? Do I need to treat them ASAP with blood stop when it happens? As I said, this is my first hatch and I'm actually sort of queasy. Thanks. I realize that this really should be under hatching/incubating - my apologies for posting in the wrong area.
