I have a 3 month old Ancona duckling that has been sick for the past few days. I went out to find him being knocked over by the other ducklings. When I picked him up he was very light. When I brought him inside he ate a bunch and drank a bunch so that made me think he was being bullied away from the food. He pooped and it was runny (I assumed from all the fluids). The last few days he has been eating less and less but drinking well. I haven't notice much for poop in his pen. Today he seemed to be straining so I picked him up and checked his bottom to find that his penis had prolapsed (and possibly his lining as well just a bit). I'm not sure if this has been the problem all along or happened because he is trying to pass small amounts of poop from not eating. I put lubricant on it and tried to gently put it back in but it didn't work. The area almost seemed hard behind the cloaca. He acts like it is painful. I have never done this before so I don't know what it's supposed to feel like. I can really get a finger in there to check for anything as he is a very small duck. He hatched out of a cracked egg and has always been a good one third smaller that his siblings. The penis and surrounding tissue are pink but the tissue seems a bit swollen. I may tube feed him tonight to get some nutrients in him. He has vitamins and electrolytes added to his water. Any help and/or input would be greatly appreciated ps I can't post pics with my phone so if someone wants pics I can send them via text and perhaps someone can post them for me.
