My pekin duck has been egg bound before where her vent prolapsed and we had to put it back inn, she has been fine for months and laying eggs. It has now happened again however this time it is swollen, full of blod and poop that is running out where it can through holes in the sack. Her beak is very warm and Greg-ish. The sack is huge and is impossible to get back inn. She has stoped shaking and panting after I gave her pain medication and put her in a warm bath. What should I do?
