Yes if the chicken side quest is in the game, the bad ending is as well.
And the satyr bad ending is related to the cursed coin quest line but is missable, so if that quest is in the game already the bad endings are as well.
If you want some hints.
Chicken quest need to be beaten for it to be able to appear on the farm.
And cursed coin quest must be done without having any sort of curse protecting key items.
Hope that helps, if not ask more^^
