Hey, we are trying to incubate eggs without an incubator or hen and were told that it would not work. Now, here we are on the 21st day and have heard little squeaks plus one of the two eggs is making little ripping noises if you put it up to your ear. Are they alive? We aren't entirely sure if we just imagined the squeaks or if they are real so put aside that fact and focus on the ripping noises which we are absolutely sure are happening. Thanks!
