One of my pretty little sebastopol geese started limping a couple weeks ago. I looked at her foot and leg but didnt see anything wrong so I just kept a close eye on her. By last week, her she was clearly struggling to walk at all. I separated her from the other geese by putting her in the duck's night pen. I again examined her leg and foot and could find nothing wrong with it. Soon, I noticed that her wing on that side was hanging quite low. After pushing all her fluffy curly feathers out of the way, I could see that she has a huge lump (the size of half an apple) on the joint of her wing "elbow". Could this be a tumor? I cannot imagine how this lump on her wing is keeping her from walking, but she is now barely using the leg on that side. I have felt all the way up the leg to the hip joint and dont feel any lumps, however my dd thought that that leg felt kind of limp in comparison to the other leg. Has anybody seen something like this before? I dont want to cull her, but I dont want her to suffer if there is no chance of recovery. Note: There are no farm/poultry vets in my area. Here are two photos of the lump. It is quite solid although I didnt press on it very much for fear of hurting her. In this photo from the front, Ive pulled her cape of feathers forward so that you can see where the lump is in relationship to her wing and shoulder. Here you can see how she is dragging her wing.
