Yes, a single head is ideal. Sometimes secondary heads follow the main one. But cauliflower is one of the most tempermental plants in the garden. Stress, such as too much heat or cold (which can prevent a head from forming) to poor soil/nutrition to lack of water to insects can inhibit successful growth. See above about this.
Before you do anything, be sure that these are in fact lateral heads, separate from the main one; be sure they are not small curds that would eventually be part of the main head if left to mature. If they indeed are separate 鈥渘ew鈥 heads, we are inclined to suggest that you could remove/cut off the side shoots to enable the main head to develop fully. Realize that this might introduce stress that would affect the entire plant. Or you could leave it alone and harvest a few smaller heads (those being the main and the laterals, later).
