So I am new to duck ownership. I have 6 ducks (4 Khaki Campbell & 2 Muscovy) who are seemingly healthy and happy. I let them free range in my yard during the day and at night put them in a covered pen. I am a hobby breeder of dogs and on occasion have a litter. I have never had an issue with Coccidia or Giardia in my puppies before but I don't want to start now. How likely are my ducks to be carrying these bacteria? When my puppies are old enough I let them venture outside in an X Pen (It would be set up in the yard which the ducks roam). Should I spray the area with a disinfectant before allowing the pups in that area? Are ducks that don't come in contact with any other animals not likely to carry this? I had a friend lose a litter of pups to Coccidia so I want to be proactive about this. I know Coccidia can be hard to get rid of out of a yard so I'd like to prevent it if it's a threat from the ducks.
