So my husband and I just finished treating one of our ducks for an infection and now, we have another problem with another one of the ducks. One of our Pekin ducks has something going on with her foot and I don't know what to do to help her. I've noticed her limping a lot lately, but every time I've looked at her foot, I haven't seen anything wrong with it. Today, I noticed that she was having trouble walking and didn't want to get up when I threw some scratch to all the ducks. She just laid there, unlike herself. When I looked at her foot, I noticed a huge knot on it sticking up on top and when I picked her up, there was a quarter-sized knot on the underside that looked like it was about to burst open. I immediately thought bumblefoot, but I knew I couldn't do anything about it until my husband could help me. We cleaned her foot when he got home and there isn't a scab on it. He took a needle and stuck it in the top of the knot, thinking that if it was infected, puss would come out. The only thing that came out was blood. He then stuck the needle in the bottom of her foot and the same thing happened. He said it felt really hot to the touch and really hard and tight. Does anyone have any idea what this is or what to do about it? I can tell she's in pain with it as it is and I don't want her to suffer. Just so you know, the two black spots on the bottom picture are where my husband stuck the needle in.
