Hi Kartay, welcome to BYC.
Congrats on your new ducks. Given they are 8 months old and were laying eggs and stopped because of the cold, they should resume laying when they deem suitable. Besides when ducks(and other fowl) move to a new home they generally stop laying for a short period until they get accustomed to the new placed and feel like it's home. That should take around 4 to 8 weeks.
By the time they get used to their new home, the weather should also be warming up with longer days. So expect eggs maybe in March/April at max. Oh and ensure they are healthy/comfortable/happy.
Keep us updated,
Cheers
