On updating the mod, I logged in to a server to find that the nest that previously contained my constantan chicken was completely empty. That chicken was found sitting on a nest containing uranium chicken drops. My uranium chicken was found sitting on a nest containing aluminum chicken drops. My aluminum chicken was gone entirely. Trying to hatch one of my aluminum eggs produced a uranium chicken. Breeding or hatching new eggs produced the correct chickens with no further issues. Another user reported that throwing a constantan chicken egg crashed the client, but produced no server crashlogs.

I need more information. like the actual version number of the mod, What type of server are you running, forge or spongeforge?
Preferably the crash log the other user was getting.

https://minecraft.curseforge.com/projects/coop-life
"Coop Life" Pack version 1.5.1 for Minecraft 1.10.2
Hatchery-1.10.2-03.17
Chickens-4.3.2 (EDITED: Corrected mod version)
MoreChickens-1.10.2-1.1.4
Forge 2316

If you want a full mod pack install to test on, you can grab "Coop Life" off the Twitch / Curse Launcher and install the latest update for it. (v1.5.1)

Crashlogs relating to this ARE incoming as well, should be posted here shortly.

Wait your using 'Chickens 4.3.1" you should be on the latest, that version had broken code?

Chickens 4.3.2 , sorry. That was a typo on my part.
