hi im having a problem with one of my eggs. well, i noticed it had made a small pip in the shell but after that, it didnt move ! i was tempted to help it so i did. i removed the top of the shell leaving the membrane exposed and increased the humidity. i also covered it in wet tissue except the pipped area. i can see its feathers through the membrane and it looks mostly developed but it wasnt moving the entire time i was removing some shell. when i looked at the membrane the next day, it turned yellowish, like a light iodine colour. i dont know if my chick is dead and what to do. HELP!
