Hello! I have a batch of 12 California Quail. It is my first time hatching quail. I've monitored their development by checking them with a candler and everything seemed to be developing great (I stopped candling about a week ago in oder for them to prepare for the lockdown period). We are now on day 24 and I don't see any signs of pipping and I'm nervous to check them because I know how fragile this lockdown period is. Is there a way I can check to see if they are still alive without taking them out of the incubator? Is 24 days common for California quail? How much longer should I wait before I call it?
