I have a 3 month old Jersey Giant who has a large red lump on her head beside the left side of her comb directly above her eye. Her wattle and comb are bright red. She's eating and drinking and doesn't seem to be affected. I managed to grab her and take a close look and the lump is soft and feels like it is full of fluid. When I pressed it a thick clear liquid came out right at the base of the lump. Does anyone have any advice on what this could be?
