So I've looked through all the duck prolapse threads but only have found information about actual prolapses-where it stays out. I'm wondering if anyone has information on what would cause it to come out each time he poops? It might take a minute but he can wiggle his but and it retracts. I feel like this shouldn't happen...Also, his poop seems to be pretty watery, often enough that he does get some dirty vent feathers. Has anyone else experienced this?
