Elise couldn't contain her excitement and curiosity and came too close to the egg. And it was perfect distance for the egg to suck her. She noticed in that moment that it started to suck her, but it was too late. She was sucked into the egg as it had happened to Edwin.
The egg would soon hatch, so it didn't had enough time to convert her. Also, it was unable to hatch multiple subjects at the same time. As a result, Edwin and Elise merged into one to hatch.
As Edwin had became a female chick, it was clear that they were going to be a female, also young, and kind of anthro chick.
Soon, they(or she? anyway they'er one now) hatched. She was only about 15 inches. She quite looked like a human girl about 6 years old, but she also had little beak and yellow down all over her body. Even her arms were more like short fingered wings than humans arms.
She started to think of herself as "Edlise", as she was partly Edwin and partly Elise. Edlise looked down herself. Her Edwin's part was shocked by "he" became "she", even became an anthro chick. At the same time, he Elise's part was regretting her careless action.
