When a chicken grows up, all other baby chickens on the block suffocate (chicken farms)

When the chicken grows up, all others die from suffocation or burning (not sure which one)

Steps to reproduce:

  1. Download the demo world

[media]
  1. and open it. Note: There are two nearly identical copies of a partial automatic chicken farm/cooker. The only difference between them is what kind of block is behind the lava blade.

  2. On each farm in turn, toggle the lever to activate the egg dispenser. After two or more chicks have hatched, toggle the lever off again.

  3. Feed seeds to one of the chicks until it turns into an adult chicken.

Expected results:
In both farms, the adult chicken gets cooked by the lava, and the remaining chicks are left alone.

Actual results:
The left farm works as expected, while in the right one the remaining chicks are burned up along with the new adult.

Workaround by [~Auldrick]

There's no easy workaround for this problem, but you can modify the farm to use a different design that doesn't trigger the bug. The block above the dispenser has to be a full-size solid block. It's probably a hopper at the moment, so you'll need to move that hopper to the back or one side of the dispenser. That will set your egg-layer chickens free, unfortunately. but you would need to move them anyway to be above the new hopper position. You may wish to look up a tutorial on YouTube that uses this alternative design.

Still in 1.16.0

Confirmed in 1.16.1 on Windows 10.

This happens in automatic chicken farms of a certain common design.  This image shows the essential parts of the design in two copies of a farm, viewed from behind.

 In the farm on the left, the block behind the lava is a hopper; on the right, it is a quartz block. The block in this specific position determines whether the bug is triggered. I have tested several kinds of blocks in this position. Full size solid blocks, such as the quartz on the right, seem to work correctly (i.e. they don't burn up the other chicks when one chick grows up). So do quartz stairs and bottom quartz slabs. Glass blocks also work correctly. Blocks I tested that do trigger the bug include the hopper, polished blackstone wall, sign, and top quartz slab.

I will add repro steps to the description and upload a demo world.
