Ok... my hen has been sitting on eggs since March 28. It’s been over 21 days. I noticed today one egg actually pipped. She stopped sitting on it. I checked it later and it had a white sack inside. You could see nothing but a white sack. No veins. I was told to use a qtip and gently put some water on. Then I checked and the sack is filled with something. It has veins in it. Something moved inside the sac. However if it pipped why isn’t the internal membrane cut??? I’m so confused. What do I do? I’m so scared it’s dying. Photo of what’s inside. A sac filled with fluid and something moving looks like. And veins of course. Help!!!!! I put it back under the hen and she’s sitting on it but I’m afraid something is wrong....
