We have a two week old buck fawn with a swollen ankle. It was born 3.5 lbs and was very weak. We pulled it, and it took to the bottle and has a good appetite. The swelling started about 5 or 6 days ago. Two days ago we gave it a 1/2 cc of Draxxin, but the swelling has not come down. It feels like it is fluid and is slightly warm to the touch. He favors the leg, not putting much pressure on it when he walks, but does not show signs of pain when I pick him up and touch or move it around. Despite the swelling, he doesn't miss a feeding. Any suggestions on how I can get the swelling down? Thanks.
