Hi. I just got ducklings for the first time. They are 2 white layer ducks and 5 days old. They are very friendly and super happy and healthy. They eat their regular duck food, drink lots of water, and tried a piece of blueberry, strawberry, and grape. (all in moderation). Today one of my little babies threw up on my hand and I believe it was clear but my first instinct was to wipe it off. I read that it is normal if they are nervous. But that wasn't my main concern. They have been getting along extremely well so I don't know if they fought and I'm always near the cage, but the same duckling had a "bald spot" underneath her head and on her neck. I left her alone after looking at it and when I came back, it seemed to have been gone for the most part. My thought is maybe that it was wet and she just has fewer feathers there, but it stayed on her chin area where she couldn't reach so maybe it was just wet? I am really concerned because before they came, my biggest concern was making sure they were happy and healthy. I will attach a photo before it was dry, it doesn't look bloody either. Please help, I have grown to love these babies so so so much. Thanks.
