Jurassic farm, farmer Indiana Smith
There's a new piece completed for players upon level 60. Mr Smith, an archeologist, has found some eggs in Egypt. How eggciting!! Professor Lucas has found a way to make the eggs grow again into dinosaurs.
The dinosaurs have to be cared for off course. Since nothing dies in Hayday, the animals behave natural and because they are fed they are just happy on their part of hayday.
New eggs must be bread by the farmer. It takes a few days to get a baby dinosaur. Since the first 2 eggs are found they don't cost you. Extra eggs will cost you vouchers. Feeding and keeping dinosaurs will get you some goodies.
Something like the dogs, horses etc.
This is how far my fantasy goes right now.
