I just hatched out 6 very healthy Texas a&m quail but the last two eggs never progressed. They were actively moving during lockdown but must of died recently. I did the float test on them and there was nothing. I decided to open them and it was a bit disturbing. They both had cross beaks and one was missing both eyes. The other only had one. Why would this happen? Genetics? Vitamin deficiency? Or something I did during incubation? Here's a picture of the two. Its really sad, sorry, but I want to figure out what happened. The others are perfect.
