New hatches teleport to different stables upon birth

So, just a bit more of observation, as it seems it may not be directly at birth. When the hatches break out of their eggs, they sit in the incubator for a while. If I manually remove them from the incubator. they go to the correct stable.

If I don't get around to removing them from the incubator manually because I'm doing other things, and they get removed automatically, they end up in the wrong stable and overcrowding it. 

checked it out for fun but couldn't see anything going wrong? eggs get hatched, the baby critters stay in the incubators untill they reach adulthood and then they are ejected on the tiles the incubator is build on.

maybe make a vid of it?

as a solution to overcrowding you could make use of the auto wrangle option. and kill off excess critters in a critter friendly manner.

that said in the save, the lowest stable was already overcrowded.

I don't know if you know this but, when an egg hatches in an incubator a dupe will take the critter from the incubator and bring the newly hatched baby critter to the appropriate stable if available. so there is no need to place the incubators in the stables.
