My duckling was attacked by a cat, sick, crusty eyes, won't eat.

Thanks for reaching out about your duck. Hydrogen peroxide kills cells indiscriminately, good and bad, and should be stopped. This duck might benefit from systemic antibiotics, since topical medications do not penetrate deeply. A veterinary visit is highly recommended, ASAP. This can provide a diagnostic/treatment plan. Provide some supplemental heat in the 75-80 F range, might help a little. Syringe offer food and water for calories and hydration. God luck.

Thanks for reaching out, this appears to be a dried wound and veterinary attention is needed, ASAP. This might require some surgical debridement. Systemic antibiotics are probably required but also protection from flystrike. Good luck.

Without knowing what caused the deaths of the rest of your flock it would be hard to recommend treatment. It sounds as if some sort of contagious issue such as bacterial infection, virus, etc may be causing the problem. It would be best to bring your drake into a local vet clinic ASAP so he can be examined to determine the cause of the illness. If you have any other birds remaining in your flock, separating out and quarantining sick birds from the healthy ones, and thoroughly cleaning all shared food, water, bedding areas may help reduce further spread.

Ducks should be fed more than just corn as feeding only one type of food can lead to nutritional imbalance and diseases with symptoms similar to what you are seeing. Ducks and chickens can be housed together, however they do have differing needs and males of one species may harm or harass the other which could lead to injury and illness. It would be best to have separate housing for each species as well as feed a balanced diet tailored to each as their nutritional needs can vary some. If you have a duck that is acting ill it is best to seek the care of a veterinarian near you as well as keep the duck away from the rest of your flock to avoid spread of illness as well as picking on the sick duck by any flock members.

Ducks can be very messy, so daily cleaning of the eye may help keep it clearer, however if at-home remedies haven't helped, having a vet take a look for any injury to the eye itself and any infection is best. They can recommend or prescribe additional treatments as needed depending on the cause.

If the duckling is wild it would be best to seek out the help of a local wildlife refuge or rehab center that can safely treat and raise the baby until it is ready to go back out into the wild. Runny eyes and sneezing can be a sign of infection or respiratory illness, so keeping the baby warm, and eating and drinking may help until you can transfer it somewhere for care.

Hi there and thank you for using Pet Coach to address your concern. The wound on the side of the mouth does not appear to be serious but if you are concerned he ate something sharp, I would take him to your nearest exotic veterinarian and have x-rays taken to see if there are any concerns on the x-rays that need to be addressed. I hope this helps! Please let me know if you have any other questions or concerns. I am also available via consultation if needed.
