Not coming in for the night

[Duckduck_Guz]

Hello, this is my first winter with my 15 ducks, couple Pekin, khaki Campbell, random mix of breeds. They have a duck house about 50 yard from our pond. I let them out in the morning and they usually come in at night. The last 4-5 days they have not been coming into the duck house. I have food, good fresh bedding, and fresh water every night for them. I can’t seem to coax them in from the off the pond, I’ve tried mealworms and making a trail of feed to the duck house. Nothing works. I don’t mind them being out there all day and night most of the time because I know they’re safe on the pond, however it’s been in the low 30s and high 20s lately and I think that’s just too cold. They’ve gone in and out of the house every night without a hitch since I got them in may of this year. What could the problem be and how do you recommend I handle the situation?

Are they eating the feed when you're not watching? Like later in the night are they coming in for the feed and going back out?

Not activity at all that I can see in the house.
