From Andrew Wooldridge's site:

From the creator of Aveyond comes a new game called Grimm's Hatchery. This looks to be a casual game where you hatch and raise pet animals such as dragons and gryphons. The artwork looks top notch, and given the great work of the previous game, this looks to be another success for its creator.

Funny that there was never an announcement in the Indiegamer forums.
