The new yield for chickens inherits from a class that is named as YieldItemCapraHircusBase. CapraHircus is the goat and not the chicken. It's minor but need to maintain proper naming.
The generic action ActionDummyContinuousRelease contains text for the fishing release action. The fishing release action should be a separate action.
These are not game breaking of course, but proper naming and usages should be followed in base game code. This will help modders (and your devs) in easier search and maintaining the code.
