Ok, I have a duck. This winter she was chased away by a dog and gone for a week. She came back with both her feet frost bitten as well as her beak. I kept her indoors for 6 weeks, cleaning medicating and pampering. She lost most of one foot before I put her out side and was able to kind of hobble around on it. The remaining foot was still black, I figured that if the second one would of fell off like the first she would be ok and still have a good life. Well it fell off and left no foot at all, just bone, and the bone is cutting in to her. I know I need to cull, I need the strength to do it. I also need to know the quickest and most humane way. She is eating and drinking but not able to walk or hobble at all, it has only been 2 days and tomorrow will be the third. She has bonded with a male muscovy and he has not left her side. I have cleaned her up each day and put salve on her to minimize her suffering. Please give me advise and strength.
