Easter Bunnies dropping empty eggs

I was in Avalon River and have found two occasions where Bunnies have have dropped an two items, 1 is a ratling egg, and the other is what I assume is to be the contents of the egg.

Thanks, do you recall the item type that dropped with the Egg?

Yes the first one was a Green Easter Egg, the second was a backpack dyed orange. I have "hunted" the bunnies in Winter Wold, Leinster/Kurz Road, Ocean View, Drear Valley, Barrens, amd Avalon River. The river is the only place I have seen this issue, amd it wasn't every time. Tonight I got around 10 eggs only two had this issue.
