We treat them all the time, there is no need to kill a bird for a prolapse unless your only purpose is to breed them. They can even sill breed with just a shorter phallus. In ducks the phallus isnt vascular and just a delivery tube so shorter the tune less effective delivery but doesn't mean no delivery.
You can use sugar to shrink the tissues or what we use is Hemorrhoid creams that will also shrink tissues and provide the lubrication to get the phallus back inside. Never put necrotic tissues back into yoru birds body so you do want to remove the dead skin first.
Just a word of warning though prolapse's are often a secondary symptom. They can be caused by trauma but the most common reason we see it is due to bacterial infection. Sometimes its just inexperience of the male to put things back and swelling blocks it and it just escalates into a bigger problem. I always run a course of antibitoics with a prolapse just to be safe.
A quick Dick update...he is doing fine so far. We kept him isolated for 2 days then put him back with his buddy. They are both new to us as we got them off craigs list.
Could stress also cause this to happen? They had a 2 hour car ride here, BUT the people that had them before thought it would be a good idea to pen them in a box in the car the day before the ride, so they spent almost 48 hours in a box in the car! What antibiotic do you recommend?
i don't know if the car ride freaked them out, as most ducks seem to not mind the car. when my ming mei was only a week old she traveled on the dash board of my moving truck from chicago to montgomery! that's 14 hours... and the ducks have made the trip back and forth from IL to AL and back again 3 more times and actually seemed to enjoy it. He's probably more freaked out by the new owners and the new surroundings. poor little guy
I believe Baytril is an antiboitic you can use for ducks. My ducks have each been on baytril for different reasons (one egg binding issue and one foot problem). I'm not sure on doses though. Mine came from a vet and was in pill form... I just snuck a round pill into a tomato or a grape everyday and tricked them into eating it.
