I'm new to ducks. We have 7 ducks and 2 geese together in our garden area separate from our hens. They are about 2 months old. Yesterday my husband said one duck looked sick. This morning While feeding everyone I noticed the duck wasn't walking but using her wings to pull along. I brought her into the house and put her in the bathroom. No visible wounds. Gave her some water, some kale and some dry cat food. I'll go get niacin and brewers yeast today. Any other recommendations?
Also my husband thinks the geese are abusing the ducks. They've been raised together. But he watches from his chair and sees the geese "standing on their backs and biting their necks". Like our roo does to the hens. Do we need to separate the geese and ducks?
