If you have received your pre-chilled bulbs in early December, they may need 4 more weeks of chilling. After January the bulbs will have received 12+ weeks of chilling, and do not require any additional chilling. If you are not able to plant your bulbs immediately upon receiving them, it is important to continue chilling them in cold storage such as a refrigerator, cold garage or cold shed until you are able to plant.
