Animals seem to suffocate when growing up near a solid block.
- Create a one block large, two block high enclosure. Use solid blocks like cobble.
- Throw chicken eggs in it until 4 chickens have spawned
- Wait until all chickens are grown up
- Count the chicken
Most of the time all of the chickens have died, sometimes 1 or 2 survive. This happens not only in tight enclosure but also randomly near walls or blocks.
If the blocks are transparent (glass, fence) the animal just can walk through.
I think this is probably due to a smaller hitbox, that is immediately enlarged, when the animal grows up.
