Hi guy, I don't joke when I sad that. I don't know why in my world, everywhere fall ecplosive chickens from the sky .-.

Anyone know how i fix this? Or what cause this?

This bug accured when i disabled some mods (Twilight Forest, MFFS, Traslocator) and when I installed Unbelieveble Shader.

This is from Ichun PortalGun Mod. It Easter Egg he added long ago. It something most forget about.

PortalGun causes raining chickens if you play on christmas day (Dec 25th).

If you have a problem with that you can:

• Open your config and set the following option to 0
• ####################
  # others
  ####################
  
  others {
  # Oh wouldn't you like to know?
  I:easterEgg=1
  }
• disable PortalGun
• or set your system time to Dec 26th temporarily

I really don't want to mess with the system time. And that option doesn't seem to exits in my config. Any other solutions?

Update: This is a client only setting. I did find it on my client and changed it.
