It'd be great if it were possible for ducks(or really any other modded critter that lays eggs in a way similar to chickens), to use the nests of Incubation like chickens do.

I don't know how feasible that is, though, so failing that, I am here to request compatibility with the Duckling mod.

Unfortunately, no plans for this at the moment. Someone is welcome to make a compatibility add-on, though.
