Yesterday was day 18, I notic d when I went to put the chicks in lockdown that one had pipped already so I quickly finished and left them alone. Today the little thing has come completely out of its shell but has this mass near its rear end. Is it ok? Gonna die? 50/50 chance? This is my first time hatching eggs. And I have 9 out of 3 1/2 dozen that made it to lock down. Most of them never even started to develop. And a couple had the blood ring. Was hoping these 9 that made would hatch with no issues.
