[SOLVED] Egg laying makes hay stacks dissappear

[SOLVED]
EDIT: think I know what happen now. The hay is not destroyed, it gets teleported to another tile it seems. There's some hay on an animal bed next to an egg, that must have got there by teleportation to make room for the egg.

------
I noticed in my chicken coop, where I have stockpile for hay that when they lay eggs and it happen to be on a tile with hay on it the hay will get removed from game, it simply disappears. I tried making a stockpile in there just for eggs, and also tried to clear some tiles so there is nothing but ground there. Additionally I made animal beds for all animals and they do sleep in them, but I have yet to see them lay eggs in them. None of this prevent them from laying eggs on tiles with hay thereby destroying it.

This means that laying five eggs can result in the destruction of up to 1000 hay (5 stacks of 200 each), which is quite excessive. Of course I can just make more hay fields... but surely this can't be intentional?

Is there any way around this bug? Im assuming it's a bug.
