It's Day 23 now. My broody hen hatched out three healthy chicks on day 21 and is still sitting on the other 2 eggs. This evening there was a small crack (but no pip) in one egg and just a very tiny amount of blood by the crack. It also looked like the egg was rocking (although maybe I imagined it). I went to the store and came back an hour later and the egg was cracked down the length and the end, the small end was all the way off. These chicks are silkie mixes and this particular egg I think was a silkie/cochin mix (silkie father, cochin mother). The membrane was visible on the end where the shell was gone. This was not at all the way the other three chicks hatched and sensing something was wrong I picked the egg up to look at it. It smelled I used a toothpick and very delicately picked the shell away a little at a time and exposed a fully formed chick, apparently dead. The small amount of yellowish fluid that leaked out smelled rotten. There wasn't really any blood. I dabbed at the chick with a q-tip and cleaned around its beak. No movement. I left the chick still partially in the egg where it was attached and laid it back under the mom. I assume its dead, but I thought if it was just tired or cold I'd put it back under mom and see what happened.... So why did it die? Does the smell mean it actually died a couple days ago? Did it drown? But if that was the case how did the crack form and the end of the shell come off? Gas pressure? Ohhhh So sad. This was my very first hatch and at least I have three happy fuzzy chicks. What about the other egg? I read to give them until day 25 and broody hen is still sitting on them. Should I pip the last egg and see what's going on? Does anyone have any advice? I feel really sad. I took a picture and will get it posted asap. Ok, here is pic.
