Just happened recently; I was outside watching my quails, when one started to lay her egg in her nesting box. After laying it, she slowly returned to her normal shape (before she was all poofed up), and then did this random but loud screech/call thing, and the male came right up to her, with the other female trailing along not far. When the male arrived, she walked away. The male has already mounted both females before if that helps... And I've cracked an egg before (accidentally, but it was tasty) laid by my other female, the eggs were fertile for sure. . . Anyone know why she did that random screech? And if it was an 'egg call', what does it mean? I've heard it means that the eggs are fertile, but how would she know?! Thanks.
