I have 11 goslings (first time) and they were are really lively when I got them the day after they hatched but now some seem a little off. One puked on me today. I'm not sure if I pushed on its stomach or what but it did but afterwards it wold shake its head and liquid kept flYing out. Some have diarrhea, but knowing waterfowl(ducks) that to me isn't a full concern. And some seem a little less full of energy as usual. They are in my room inside, so they don't get very cold. Just wondering what might be wrong... I've also noticed some have bald spots on their wings, belly and some on their neck... they get baths daily sometimes every other day. Concerned about my babies.
