You’re in such a warm zone and planted so early, the bulbs hit “go” (grow!). Had you waited until what approximates a chill sets in, the bulbs may have waited. You can cover them with a light mulch, and keep covering them as they pop up.
Presumably you planned to pull the b-sprouts and brocc stalks once they finish? You might not, as this may upset/uproot the daffs too. Instead, cut the stalks at ground level and leave until spring.
