My ducks typically scream/squawk early in the morning after laying their eggs and want to get out of their enclosure for the day and usually during the day they are active, poking around in the dirt and grass, napping for a couple hours. For the last week or so with the colder weather (I live in Rhode Island and the cold finally arrived as in 30-40 degrees during the day and teens and 20s at night), they have been quieter and napping more and more. They let me get closer to them than before when they are lying down before they decide to stand up again. However when I take out their mealworms they go nuts for them so its not an appetite issue, though they havent been drinking as much water. I havent had to refill their waterer today. Is this normal for colder weather? or could this be a more serious issue? Any tips would be great!! Thank you!
