My khaki Campbell who is not quite two years old won't eat. She has been separating herself from the flock and not eating for almost a week. She lays down and sleeps a lot. I took her to the vet yesterday and didn't get to much from them. Olive was given some meds for bacteria, yeast as a precaution and a dewormer as a precaution. She did have blood in her poop yesterday and I was told it was because of the bacteria. She is so thin (half the weight as our other khaki). Please help. I don't know what to do. We have never had to deal with a sick duck and am so worried. She has had 2 doses of her meds but she just won't eat. Any suggestions?
