This is an adult Florida Gallinule or Common Moorhen (Gallinula chloropus) with its chick… they’re a fairly common water bird in the wetlands near West Palm Beach and I would see them quite often, but for a little while I was able to see them with their chicks… (I have some videos that might see the light of day here at some point too!). That chick has to be pretty young with that bald head and barely developed wings.
