0004637: Elk birds starve to death trying to hatch eggs because of [GRAZER] tag.
Summary says it all. I caught and tamed a bunch of elk birds, made a pasture for them, added some hatching boxes, the females run to the hatching boxes, lay eggs and slowly starve to death trying to hatch them.
Catch elk birds. Put elk birds in pasture. Put nest box in pasture. Watch female elk birds starve to death.
Obviously this goes away if you remove the grazing tag from the raws.

Acknowledging this - don't believe it requires a save.

I think the grazing fixes in 0.40.13 have fixed this. Five elk bird hatchlings just hatched in my vanilla 0.40.22 fortress (though the eggs were laid in an earlier version).

K, we'll call it fixed.

Please PM a manager on the forums (or reopen the report) if this problem is still present in the latest version.

Confirmed in v0.40.24.

While they *may* survive if their eggs hatch and they don't immediately lay more, I had 3/3 starve in one year with unfertilized eggs. And that was with occasional flying critters scaring them halfway across the map. Dwarves would drag them back to their pasture and they would immediately return to their hunger strike atop the nest box.

Relation could be established to 0004018 and 0007933 since grazers don't path towards grass with the intention of eating it, as much as randomly meander and eat grass underneath their tile randomly.

A fix the player can do themselves is to raise grazer co-efficient then station the egg boxes over lush areas of grass to reduce consumption, but that workaround renders grazing pointless.

Or alternatively take the elk bird aside into a cage, feed with dwarves on cage feeding labours then release back into pasture onto the eggs, but that requires micromanagement.
