0011257: Animals not using nest boxes
I've made a couple fortresses now and can't seem to get chickens to use nest boxes the way they used to. I've designated a pasture area over the boxes, put hens in the pasture (and I do have roosters), but none of the boxes get claimed.
Try to get a chicken to claim a nest box.

Here's a bugged save: http://dffd.bay12games.com/file.php?id=14693 [^]

An update: After playing further, I'm not sure this is actually a bug. It seems to take a lot longer than it used to for them to claim nest boxes - unsure why - but after about a year, one of the hens did claim a nest box. If that amount of time is a bug, then this could stay open, otherwise I'd mark this as closed.

They should be laying infertile eggs regardless providing you aren't clearing them away. If they're only laying on impregnation, that's a bug in itself compared to previous version's behaviour.

They don't seem to be hatching eggs at all. Even after claiming the boxes, they don't lay any eggs before they wander back off into the pasture. After a time, the boxes become unclaimed again.

At year five, the hens are finally using nestboxes. Not sure why it took so long for them to start, but it does mean that this can potentially be closed.

I have tried this save and you have a hen egg barrel on your zlevel 8 food stockpile 5th row from the top, if eggs are being collected to stockpiles (which can be filtered by using stockpile settings, which havent been used as they are set to all food) dwarves will take them away and not allow them to fertilize or poultry to sit upon.

Relevant breeding advice on the wiki involves usually forbidding doors so that dwarves do not path to take fertilized and unfertilized eggs before they hatch when a stockpile is open to deposit to.
