How many have you treated..? I'm rather curious..?You're missing the point I think. You are basing your advice on the one prolapse that you treated. You treated with Vaseline for some number of days, it did not go back in so you cut him loose and dealt with it two months later. Only the tip died, he lived, and he can still breed. Do you really want to claim that as a valid treatment plan? What are you gonna say to someone when their duck dies from sepsis from using you method?
