Problem with fertilized chicken eggs

[Anfi0312]

I have run into a problem with chicken breeding. As soon as a fertilized egg progresses to 100% it does not spawn a chick but the log displays the following error over and over again:

Code Select Expand

Without mods it is working like intended. So it must be caused by one of the mods I'm using. I searched for other people reporting this problem but to no avail.

I would first test by removing mods one-by-one which modify the core animals.  I suspect one of those is the culprit.  Once you can determine which one is at fault, post the issue in that mods forum thread so the mod author can address the issue.

[RawCode]

download notepad++
navigate to mods folder
invoke Find in Files... routine
your keyword is "chiken" or similar (open coremod and check name of chinken pawn entry)
remove any mod that have any type of reference to chickens

report back to this thread with updated info
