I have a Pilgrim gander, just about 6 months old who isn't doing well this evening. He was just sitting on the ground, and when he gets up he moves very slowly, and his breast/crop area seems swollen. It doesn't feel hard or squishy, just bigger- enough that it's obvious, if that makes sense. His eyes are bright, nasal looks normal, I don't hear any rattling/respiratory anything, he's just 'off'. Moving very slowly, he was WAY to easy to catch . He was fine yesterday, and the rest of his gaggle (mom, dad, and 2 sisters) are acting fine and normal tonight. I'd appreciate any advice. We sure do hate to see our Mr. Bean sad/sick.
